1. What is the formula for calculating the speed of a wave?

Assuming that your answers in the data table above have sound traveling 343m/s at 20°C for each of the tuning forks. If a wave's speed is constant does the wavelength and frequency also have to be constant Explain.

2.____ determines (effects/impacts) the speed of a sound wave travels through?

3. What state of matter transmits sound the best?

4. When a wave is traveling through a medium, its speed _____ until it enters a different medium.

5. If you did this lab in the summer when it is warmer how would the speed change? In another words, how does the temperature of a medium affect the speed of sound? Explain.

6. If you were to test the speed of sound in the air and compare it to the speed of sound in the metal rail of a railroad bed, which one would be faster? In another word, how does the density of a medium affect the speed of
sound? Explain.

7. How does the elasticity of a medium affect the speed of sound? Explain.

8. After comparing the actual speed of sound from the tuning forks you have determined in Part B to the speed of sound you have extrapolated for the room's temperature in Part A, what factors would have caused the
different speed for each tuning fork?

9. Describe the trend between the length of the air column and the frequency of the tuning fork.

10. Describe the trend between the wavelength and the frequency of the tuning fork.

11. Describe the relationship between the length of the air column and the wavelength.
