Question

Match List - I (Electromagnetic wave type) with List - II (Its association /application) and select the correct option from the the choices given below the lists:
$\begin{array}{cccc}& \text{List - I}& & \text{List - II}\\ \left(a\right)& \text{Infrared waves}& \left(i\right)& \text{To treat muscular strain}\\ \left(b\right)& \text{Radio waves}& \left(ii\right)& \text{For broadcasting}\\ \left(c\right)& \text{X - rays}& \left(iii\right)& \text{To detect fracture of bones}\\ \left(d\right)& \text{Ultraviolet}& \left(iv\right)& \text{Absorbed by the ozone layer}\\ & & & \text{of the atmosphere}\end{array}$

• A. $\left(a\right)\to \left(i\right);\left(b\right)\to \left(ii\right);\left(c\right)\to \left(iii\right);\left(d\right)\to \left(iv\right)$
• B. $\left(a\right)\to \left(iv\right);\left(b\right)\to \left(iii\right);\left(c\right)\to \left(ii\right);\left(d\right)\to \left(i\right)$
• C. $\left(a\right)\to \left(i\right);\left(b\right)\to \left(ii\right);\left(c\right)\to \left(iv\right);\left(d\right)\to \left(iii\right)$
• D. $\left(a\right)\to \left(iii\right);\left(b\right)\to \left(ii\right);\left(c\right)\to \left(i\right);\left(d\right)\to \left(iv\right)$

Answer 1

The correct option is A $\left(a\right)\to \left(i\right);\left(b\right)\to \left(ii\right);\left(c\right)\to \left(iii\right);\left(d\right)\to \left(iv\right)$

Infrared waves → To treat muscular strain
Radio waves → for broadcasting
X-rays → To detect fracture of bones
Ultraviolet rays → Absorbed by the ozone layer of the atmosphere

So, $\left(a\right)\to \left(i\right);\left(b\right)\to \left(ii\right);\left(c\right)\to \left(iii\right);\left(d\right)\to \left(iv\right)$

Hence, option $D$ is correct.
