Question

Answer the following:

1. Is sound a mechanical or electromagnetic wave?
2. Is sound a transverse or longitudinal wave?
3. What part of your ear receives the sound waves and turns them into electrical energy that
travels to your brain?
4.Label a compression region and a rarefaction region on the diagram below: I
5. If the speed of sound is constant, what happens to the wavelength when the frequency
increases?
6. Rank the following materials from fastest to slowest speed of sound traveling through it:
liquids, gases, solids.

Answer 1

1. Mechanical wave

2. Longitudinal wave

3. The cochlea

4. The diagram is not attached so far

5. the wavelength decreases.

6. slowest through gases, faster through liquids, and fastest through solids. or simply solids>liquids>gases

Step-by-step explanation:

Greetings!!

1. Waves in water and sound waves in air are two examples of mechanical waves. Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma.

2. Sound is a longitudinal wave.

3. The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

4.

5. As the frequency increases, the wavelength decreases.

6. The Speed of Sound: Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.

Hope it helps!!!!
