doppler's effect in light waves

JEE Advanced 2015 Help › Optics questions › doppler's effect in light waves

when light travels from one medium to other its speed changes but whether its colour changes or not i.e. whether colour is determined by frequency of wave or its wavelenght
secondly we have done in dopplers effect that since speed decreases frequency decreases
but on change of medium frequency remains constant

please explian where i am wrong
