Question

Match List I(Electromagnetic radiation) with List II(Approximate wavelength in metre) and select the correct answer using the codes given the lists.

List I	List II
A. Infrared radiation	$1$. ${10}^{-12}$
B. X-rays	$2$. ${10}^{-5}$
C. Ultraviolet radiation	$3$. ${10}^{-10}$
D. Gamma rays	$4$. ${10}^{-8}$

• A. A-$2$, B-$3$, C-$4$, D-$1$
• B. A-$1$, B-$4$, C-$3$, D-$2$
• C. A-$1$, B-$3$, C-$4$, D-$2$
• D. A-$2$, B-$4$, C-$3$, D-$1$

Answer 1

The correct option is A A-$2$, B-$3$, C-$4$, D-$1$

The EM radiation with decreasing range of wavelength are,

Infrared > UV > X-rays > Gamma-rays

So option A is correct.
