Question

How does the wavelength of electromagnetic radiation differ from its frequency?

Answer 1

Have a look if it is understandable.

Explanation:

Frequency tells you how many times your wave oscillates in `1` second, so, say, a frequency of `3 Hz` tells you that your wave 3 complete oscillations in 1 second.

Wavelength is the measure of the length of one complete wave.

Consider looking at waves in water:

You can count the number of crests passing a certain mark in one second; this is frequency.

You can take a snapshot with your camera of the wave with a ruler in front of it to measure the distance between two consecutive crests; this is wavelength.
