Discovering the speed of sound in air worksheet

Sounds, whether from talking, music, an earthquake, a fire or a sonic boom, travel in waves. Wave travel, called propagationhas a different velocity through each material, like water or air. Frequency is the number of times an event occurs per unit of time. For sound, the frequency is measured in Hertzabbreviated Hzwhich means is period cycle, from the top of one wave to another, per second.

Humans can normally hear anywhere from 20Hz to Hz, while dogs can hear up to 60, Hz, and some bats can hear sound as low as 1 Hz. Sound is perceived in pitch ; higher frequencies sound like higher pitches like a whistle and lower frequencies have lower pitches like a tuba. A tuning fork is an object that resonatesor vibrates, at a specific frequency and pitch.

The sound of a tuning fork depends on the length of the prongs and can be used to tune musical instruments. Compare your experimental value to the true value.

If it is warmer, the speed will be faster. The change in sound in the water column will occur when the graduated cylinder produces the same resonance as the tuning fork.

Simply put, this means that one period of the wave goes to the bottom of the cylinder and back in the same amount of time it takes for the tuning fork to vibrate one time. The fundamental frequency is the frequency of one period of a wavelength. The second harmonic, also called the 1 st overtone, is an integer whole number multiple of the fundamental frequency. Many people will not hear the difference between harmonics, but they are commonly used in music, and examples of harmonics can even be found in the human voice.

Wavelength is the length in meters of one period of the wave, from peak to peak. Bookmark this to easily find it later. Then send your curated collection to your children, or put together your own custom lesson plan.

Problem: Calculate the speed of sound in air. Materials: Tuning fork with known frequency Large, tall cylindrical glass container Water Rubber mallet Ruler Procedure Fill the glass container halfway up with water. Strike the tuning fork with the rubber mallet.

Why should you use a mallet to strike the tuning for rather than a hard surface like a table? Hold the tuning fork over the opening of the glass container as pictured.Forgot Password?

With the Discovering the Speed of Sound in Air Kit for physical science and physics, accurately determine the average speed of sound in air. Simple activity is easy to do and yields great results. Resources Discovering the Speed of Sound in Air. Other Options. Product Details Accurately determine the average speed of sound in air with this elegant activity!

Discovering the Speed of Sound in Air kit comes with the necessary tubes and rubber stopper for one group of students, while the classroom set includes enough materials for eight groups of students.

Each kit comes complete with student activity sheets, detailed Teacher Notes, and sample data. The experiment requires the use of a tuning fork set ranging from Hz to Hz, which can be shared among student groups.

Tuning fork set is sold separately. A support stand and two extension clamps are also needed but not included. Specifications Materials Included in Kit: Cellulose acetate butyrate tubing, 1" i.Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies.

The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. Engineers apply their understanding of sound waves, wavelength, frequency and pitch in the design of theaters and auditoriums.

Acoustical engineers use their understanding of the physics of sound to create products that maximize the sound output with good quality. Noise-canceling headphones are designed to cancel out wavelengths that come from outside the headphones. Engineers use the properties of sound when designing auditoriums and theaters to make sure that people located anywhere in the room can hear the sound well.

Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards.

In the ASN, standards are hierarchically structured: first by source; e. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.

Grades 9 - Do you agree with this alignment? Thanks for your feedback! Alignment agreement: Thanks for your feedback! View aligned curriculum. Students learn about sound with an introduction to the concept of frequency and how it applies to musical sounds. Students gain a good knowledge base as to how sound and music are related, and what distinguishes them from each other. They come to understand that sound is a form of energy that travels through a medium.

Through demonstrations and experiences with glass bottles, tuning forks and stringed instrumen Students learn about the types of seismic waves produced by earthquakes and how they move through the Earth. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.

Students learn about the types of waves and how they change direction, as well as basic wave properties such as wavelength, frequency, amplitude and speed.

Sound Resonance: How to Calculate Speed of Sound

During the presentation of lecture information on wave characteristics and properties, students take notes using a handout. Ability to do simple mathematical calculations and use a meter stick for measuring A knowledge of waves is helpful, but not required. How do we measure sound? We use a volume knob to adjust how loud it is, but what is the difference between these two sounds?

Strike two different tuning forks so students can listen to each.This seems to be the most common discussion regarding the recent Red Bull Stratos Jump. Unless you have been living under a rock lately, you have probably seen the awesome jump fromfeet. Here is a great summary video to get you pumped up. AH HA! My physics textbook says this is the speed of sound, so there. Well, not so fast. Sound is a pretty complicated thing.

First, let me talk about just sound in air. Of course you can have sound waves underwater hello submarines and even through solids. But think of air. At one level, air is made up of a whole bunch of tiny particles.

Oh sure, it is really more complicated than just tiny air particles. It is mostly nitrogen gas N 2 with some oxygen. But in this model of sound waves, it is fine to think of them all as just small particles. What happens if you take a whole bunch of these particles and push them all at the same time? Well, the pushed particles will go a little ways, but they will collide with other air particles and push them.

Those particles will collide with more and so on and so on. This is what we call a wave. The important thing to realize is that the air isn't moving very far, but the compression is moving.

Here is my attempt at a diagram showing this. Another great example of this is the wave in a football stadium. Here is an example in case you have no idea what I am talking about. What goes around the stadium? The people?

No, they just move up and down. It is the disturbance that moves as the wave. The same is true for sound waves in air. OK, but that is just a simple model of sound. How fast is the sound wave in air? Let's look back a the wave of people in a football stadium. What would make this speed change? Two things could clearly make a difference.Search for:. Home Science of Sound Sound What is sound?
