I was studying light and had a doubt that when refraction occurs (rarer to denser just assuming) then frequency remains same but lambda (wavelength) and velocity decrease. But I cant quite figure out what happens to the time period. does it increase because velocity decreases.

The frequency is the inverse of the period. So since the frequency is the same the period is also the same
