Which of the following has more energy?

A photon of ultraviolet radiation has more energy compared to photons of infrared light, blue light, and red light due to its position on the electromagnetic spectrum. Energy of a photon is directly related to its frequency, which is determined by its wavelength.

Ultraviolet radiation has a shorter wavelength and higher frequency than both infrared light and visible light (including blue and red). This means that ultraviolet photons carry more energy than photons from other regions of the spectrum, such as infrared, which has a longer wavelength and lower frequency, and both blue light and red light, which fall under visible light's range.

This characteristic energy difference has significant implications in various fields, including environmental science and healthcare, as ultraviolet light can lead to chemical reactions and biological effects that infrared and visible light photons cannot.
