Select the correct answer
A periodic wave travels from one medium to another. Which pair of variables are likely to change in the process?
A
velocity and wavelength
B
velocity and frequency
C
frequency and wavelength
D.
Frequency and Phase
E.
Wavelength and phase

When a ray of light moves from one medium to another, the ray of light changes the direction when it enters the second medium, refraction of light occurs.

When it changes the direction, the frequency will remain the same because it depends only on the source not on the medium.

As the refractive index of two medium is not same, it means the wavelength will change.

Also, speed = frequency × wavelength

So, wavelength and velocity changes. Hence, the correct option is (a).
