8. A submarine emits a sound pulse at 750 Hz that bounces off an enemy sub and returns 2.5 seconds after it is emitted. (Consider the speed of sound in water to be 1490 m/s)

a. What is the wavelength (λ) of the sound waves?

b. What is the period (T) of the sound waves?

9. The speed of light in air is 3.00 × 10⁸ m/s. In glycerin, it is 2.04 × 10⁸ m/s. A red laser, emitting light of frequency 4.3 × 10¹⁴ Hz is shone from the air into the glycerin.

a. What is the wavelength of the red light in air?

b. What is the wavelength of the red light in glycerin?
