in terms of quantum energy, how does visible light compared to UV and Infra red light

1 answer

In terms of quantum energy, visible light has less energy than both UV (ultraviolet) and infrared light.

Visible light ranges from approximately 400 to 700 nanometers (nm) in wavelength, and it is associated with a range of colors that the human eye can perceive. It is located in the middle of the electromagnetic spectrum.

UV light has shorter wavelengths than visible light, ranging from approximately 10 to 400 nm. Due to its shorter wavelengths and higher energy, UV light can cause damage to DNA and cells, leading to sunburns and an increased risk of skin cancer.

On the other hand, infrared light has longer wavelengths than visible light, ranging from approximately 700 nm to 1 millimeter. Infrared radiation is commonly associated with heat and is used in technologies such as night vision devices and remote controls.

Therefore, UV light has a higher quantum energy than visible light, while infrared light has lower quantum energy than visible light.
