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. which radiation has a higher frequency than visible light?

The right answer is Ultraviolet, X-ray and gamma radiations.

The relation between the wavelength and the frequency is thus:

λ = c / f

Previous relationship involves that the wavelength is inversely proportional to the frequency, and therefore that it is even higher than the frequency is weak, and vice versa.

High frequency (low wavelength) waves correspond to Ultraviolet, X-ray and gamma radiations.
