Do reflection and refraction through a glass slab have same wavelength

The slower wave velocity over the glass block is clearly seen to result in a shorter wavelength for the waves. They have to have the same frequency since the same number are passing by any second, so if the speed is less the wavelength must be less. However, perhaps not so noticeable is a weak reflected wave.

hey
the wave length is not same in both reflection and refraction..
In reflection the wavelength doesn't change but In refraction the wavelength changes because of change in speed of light and change of direction (either towards or away from the normal)
so the wavelength is differ in both the cases
