When entering from a rarer to a denser medium, the speed of light decreases.I know that the frequency remains constant.But if frequency is cycles/sec then doesn't that mean more speed will lead to more cycles/sec? and if the wavelength changes, should i see a different color all together? I'm not familiar with the 'complicated math' so is there another way to understand?

How can frequency be constant during refraction?
