Question

Match List-I (Electromagnetic wave type) with List-II (its association/application) and select the correct option from the choices given below the lists.

$\begin{array}{cc}\text{List-I}& \text{List-II}\\ \text{(P) Infrared waves}& \text{(i) To treat muscular strain}\\ \text{(Q) Radio waves}& \text{(ii) For broadcasting}\\ \text{(R) X-rays}& \text{(iii) To detect fracture of bones}\\ \text{(S) Ultraviolet rays}& \text{(iv) Absorbed by the ozone layer of the atmosphere}\end{array}$

• A. $P-\left(i\right),Q-\left(ii\right),R-\left(iii\right),S-\left(iv\right)$
• B. $P-\left(iv\right),Q-\left(iii\right),R-\left(ii\right),S-\left(i\right)$
• C. $P-\left(i\right),Q-\left(ii\right),R-\left(iv\right),S-\left(iii\right)$
• D. $P-\left(iii\right),Q-\left(ii\right),R-\left(i\right),S-\left(iv\right)$

Answer 1

The correct option is A $P-\left(i\right),Q-\left(ii\right),R-\left(iii\right),S-\left(iv\right)$

1. Infrared waves are use to treat muscular strain. Infrared light improves the circulation of oxygen-rich blood in the body, promoting faster healing of deep tissues and relieving pain.
2. Radio waves are used for broadcasting.
3. X-rays are used to detect the fracture of bones.
4. Ultraviolet rays are absorbed by the ozone layer of the atmosphere.

Hence, $\left(A\right)$ is the correct answer.
