Question

If the frequency of an electromagnetic wave increases, does the number of waves passing by you increase, decrease, or stay the same? a. The number of waves passing by stays the same because the speed of light stays the same.
b. The number of waves passing by increases because the speed of light increases.
c. The number of waves passing by decreases because the speed of light decreases.
d. The number of waves passing by increases because the speed of light stays the same.

Answer 1

Answer:

option(d)

Explanation:

The frequency of a wave is the property of the source of wave.

The velocity of all the electromagnetic waves is same as the speed of light. It only changes as the light passes through one medium to another.

The frequency is defined as the number of waves coming out from the source in 1 second.

As the frequency of wave increases, the number of wave coming per second increases.

So, the number of waves passing by increases but the speed remains same.

Option (d)
