Question

Humans can sense ultraviolet, infrared, and visible light. false true description

Answer 1

Humans can see the visible light but not the infrared and ultraviolet light. That is because visible light has shorter wavelength compared to infrared and ultraviolet's longer wavelength. The eyes cannot detect or see the spectrum that has longer wavelengths. Moreover, ultraviolet and infrared light can be only be seen by the eye with the help of technology.

Answer 2

False

Step-by-step explanation:

Ultraviolet, infrared and visible light are all parts of the electromagnetic spectrum of radiation. They are all electromagnetic waves, characterized by different wavelengths:

- Ultraviolet have wavelength between approximately 10 nm and 400 nm

- Visible light have wavelength between approximately 400 nm and 780 nm

- Infrared have wavelength between approximately 800 nm and 1100 nm

The human eye is able to see only a part of the electromagnetic spectrum, which corresponds to the visible light part, while it is not able to see ultraviolet nor infrared radiation.
