Light is an electromagnetic wave and it has a place on the electromagnetic spectrum based on it energy and

wavelength. How does light's energy compare to the energy of other forms of electromagnetic waves?

A)

Light is less energetic than X-rays.

B)

Light is more energetic than X-rays.

Light is the least energetic electromagnetic wave.

D)

Light is the most energetic electromagnetic wave.

Light is less energetic than X-rays.

Explanation:

The electromagnetic spectrum refers to the range of wavelengths or frequencies over which electromagnetic radiation extends. It is the entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light. In the electromagnetic spectrum, the entire distribution of electromagnetic radiation is done according to their frequency or wavelength.

The energy of an electromagnetic wave depends on its frequency and wavelength. The shorter the wavelength, the greater the energy of the electromagnetic wave but the larger frequency, the greater the energy of the electromagnetic wave.

X-rays has a frequency of about 1*10^20 Hz compared to visible light of frequency of about 1*10^15 Hz. Hence X-rays, having a larger frequency, is more energetic than visible light.
