Which one of the following statements with regard to the ultraviolet light is not correct?
General KnowledgePhysics
- AIt is an electromagnetic wave.
- BIt can travel through vacuum.
- CIt is a longitudinal wave.
- DIts wavelength is shorter/smaller than that of visible light.
Explanation
Ultraviolet light is an electromagnetic wave that travels through vacuum at the speed of light, with a wavelength shorter than that of visible light — so statements A, B and D are correct. But all electromagnetic waves are transverse waves, not longitudinal ones. Statement C is therefore not correct.
