Which of the following types of electromagnetic radiation have higher frequencies than visible light and which have shorter freq
natta225 [31]

Answer:

Higher frequency than visible light -  <em>Ultraviolet light, X-rays, and Gamma rays</em>

Lower frequency than visible light - <em>Infrared radiation, microwaves, and Radio waves</em>

Explanation:

The frequencies of electromagnetic radiations vary according to their wavelengths. The relationship between the frequency and wavelength of the waves is expressed such that:

      λ = c/f, where λ = wavelength, c = speed of light, and f = frequency.

Thus, there is an inverse relationship between the wavelength and the frequency of electromagnetic waves.

The order of the electromagnetic waves based on their frequency from the lowest to the highest is <em>radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma-rays</em>

<u>Hence, electromagnetic waves with higher frequencies than visible light include ul</u><u><em>traviolet light, X-rays, and Gamma rays </em></u><u>while those with lower frequencies include </u><u><em>Infrared radiation, microwaves, and Radio waves. </em></u>
