A. Wavelength of microwaves is greater than that of ultraviolet rays.
B. The wavelength of infrared rays is lesser than that of ultraviolet rays.
C. The wavelength of microwaves is lesser than that of infrared rays
D. Gamma ray has shortest wavelength in the electomagnetic specturum
Choose the correct option.

Options

A. A and are true
B. C and D are true
C. A and C are true
D. A and D are true

Answer

D

Explanation

The wavelength order of the given types of waves are given below
Waves wavelength Rnge (in mete)
Gamma rays `10^(-14)-10^(-10)`
IR =rays `7xx10^(-7)=10^(-3)`
UV-rays `10^(-9)-4xx10^(-7)`
Microwave `10^(-4)-10^(@)`
Hence statements (A) and (D) are correct.
