Visible light represents a very small portion of the electromagnetic spectrum. Radiation to the left in the image, such as microwaves, has a longer wavelength than visible light. Radiation to the right has a shorter wavelength than is observable.

Question

Which radiation has a higher frequency than visible light?
Responses
A X-RaysX-Rays
B Infrared lightInfrared light
C microwave radiationmicrowave radiation
D the frequency of all radiation is the same

Answer 1

A. X-Rays

X-rays have a higher frequency than visible light. The frequency of electromagnetic radiation increases as the wavelength decreases, so radiation to the right of visible light on the spectrum (such as X-rays) has a higher frequency.
