Question

Put following waves in order of their increasing wavelength:

X-rays, UV rays, Infrared rays, Cosmic rays.

Answer 1

Order of electromagnetic waves based on wavelength:

Cosmic rays $<$ X-rays $<$ UV rays $<$ Infrared rays

Electromagnetic Waves	Wavelengths Range
Cosmic rays	$<$.01 nm
X-rays	.01 to 10 nm
UV-rays	400 to 1nm
Infrared rays	700 to 105 nm

nm = nanometer = 10^-9m
