Which of the following electromagnetic waves has the shortest wavelength? A. visible light waves B. ultraviolet waves C. microwaves D. infrared waves
Well, We know that microwaves and infrared waves (C and D) have longer wavelengths than visible light. We know that UV light will give you a sunburn if you get too much of it. Therefore, UV light has more energy, and thus a shorter wavelength than visible light. Option B is the correct answer.
