Front

List the electromagnetic waves in order of decreasing frequency.

Back

X-rays, ultraviolet rays, visible light, infrared rays, microwaves, radio waves.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases.
