Question

What is the speed of an electromagnetic wave with a frequency of 100 MHz as it travels through a vacuum?

Less than c

Depends on its wavelength

Greater than c

Equal to c

Answer 1

Answer #1

All the electromagnetic waves travelling in vacuum with the same speed that is speed of light c.

Here the electromagnetic wave is travelling in vacuum so its speed is equal to c.

Option d is correct

Answer 2
