Signal waves doesnot have the enegy to carry over a long ditance.so the signal waves are mixed wave mixed with high energy carrier waves by its ampltude.that is called amplitude modulation. Modulation index=change in amplitude/original amplitude=4/6=0.666

why the frequency of light does not change when it entered into the denser medium ?

This is because frequency is the inherent property of any matter. It is fixed and specific for a particular substance. It doesn't vary as its the 'identity' of a particle or a wave.
