Determine whether each statement concerning different wavelengths of light is true or false.

Light with a wavelength of 100 nm is completely absorbed by the atmosphere.
Light with a wavelength of 400 nm has the color of red.
Light with a wavelength of 280 nm is in the ultraviolet region.

Light with a wavelength of 100 nm is completely absorbed by the atmosphere. True

Light with a wavelength of 400 nm has the color of red. False

Light with a wavelength of 280 nm is in the ultraviolet region. False

Explanation:

Light of wavelength 0-100nm can be absorbed by the earths atmosphere

Ultraviolet light ranges between 320-400nm hence the statement above is false.

The wavelength of red colour is around 620-700nm hence the statement above is false.
