Answer:
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.
