Question

Which statement best describes ultraviolet waves? They are higher energy than X–rays. lower energy than microwaves. higher energy than visible light. lower energy than radio waves.

Answer 1

Higher energy than visible light.

Answer 2

Answer: higher energy than visible light. l

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light.

The Electromagnetic spectrum involves gamma rays , X rays, ultra violet rays, visible rays, infrared rays, micro waves and radio waves which are arranged in order of increasing wavelength and decreasing frequency.

The relationship between energy and wavelength of the wave follows the equation:

$E=\frac{hc}{\lambda}$

where,

E = Energy of the wave

c = speed of light  

$\lambda$ = wavelength of the wave

From the above relation, it is visible that wavelength and energy follow inverse relation. Thus the order of decreasing energy for waves is gamma rays , X rays, ultra violet rays, visible rays, infrared rays, micro waves and radio waves.
