Question

Among wavevelocity, frequency and wavelength, name the quantity that remains constant even when the wave travels from one medium to another​

Answer 1

Answer:

Among wave velocity, frequency and wavelength, the quantity that remains constant even when the wave travels from one medium to another​ is frequency .

Explanation:

We know that v = f λ, where v is the speed at which light travels, f the frequency and λ wavelength. When medium is changed the wavelength changes, but the source emitting light remains the same and hence the frequency remains same as frequency of a wave depends on the source of the medium.

And to compensate for the changing wavelength the speed will also change.
