Sir refraction ma frequency change kina hudaina teha ta speed and wavelength ta change hunxa sir
Frequency of wave is property of source .it only changes when there is certain change from source . We know v=¥f when medium changes the wavelength changes which also changes the velocity keeping the frequency same.
