Question

Arrange the following kinds of electromagnetic radiation in order of increasing wavelength: infrared , green light, red light, radio waves, X rays, ultraviolet light.

Answer 1

The order and range of wavelength in cm

X- rays----------10⁻⁶ and above

ultraviolet--------- 10⁻⁵ to 10⁻⁶

green light---------- 10⁻⁴ to 10⁻⁵

red light--------------- 10⁻⁴ to 10⁻⁵

Infra red---------------- 10⁻²

radio waves------------- 1 to 100

The shortest wavelength is of x-rays and the longest of all is radio waves .

The order of wavelength

X-ray< ultraviolet < green light < red light < infra red < radio wave
