When sound travels from air into water, does the frequency of the wave change? The wavelength? The speed?

How does refractive index changes, when wavelength of light increases ?

Define the wavelength of a sound wave. How is it related to the frequency and the wave spreed ?

(A): When a sound source moves towards observer, then frequency of sound increases. (R): Wavelength of sound in medium towards observer is decreased.

How does the width of the chest change when air is inspired or exhaled?

A sound wave of frequency v Hz initially travels a distance of 1 km in air , then , it gets reflected into a water reservoir of depth 600 m . The frequency of the wave at the bottom of the reservoir is V_("air " ) = 340 m//s V _( " water ") = 1484 m//s)

If sound travels in the form of a wave then what is the pattern?

(a) When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency. Explain why? (b) When light travels from a rarer to a denser medium, the speed decreases. Does the reduction in speed imply a reduction in the energy carried by the light wave? (c) In the wave picture of light, intensity of light is determined by the square of the amplitude of the wave. What determines the intensity of light in the photon picture of light

High frequency sound waves vibrate the basilar membrane

A sound wave travels at a speed of 340 m/s. If its wavelength is 2 cm, what is the frequency of the wave ? Will it be in the audible range ?
