Answer to Problem 13Q

Solution:

The amplitude modulation is using.

Explanation of Solution

It is amplitude modulation. We create a signal or modulate the signal by changing the signal strength. However, in FM we change the frequency of the signal. Frequency of light determines its color. When we switch the light on and off, we change its amplitude from zero to maximum. Frequency of carrier wave is frequency of light.
