To consider we have two equations of relation between frequency, wavelength and speed,
E = h * frequency
Here E i.e. energy of photon is dependent on h and frequency where h is constant and hence whenever light enters from one medium to another medium let's consider energy and frequency gonna matter for any change. Energy of photon remains constant and hence frequency.
