Answer
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
