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

Options

  1. A{(a)(b)(c)(d)(iv)(iii)(ii)(i)\begin{cases}\left(\text{a}\right) & \left(\text{b}\right) & \left(\text{c}\right) & \left(\text{d}\right) \\ \left(\text{iv}\right) & \left(\text{iii}\right) & \left(\text{ii}\right) & \left(\text{i}\right)\end{cases}
  2. B{(a)(b)(c)(d)(i)(ii)(iv)(iii)\begin{cases}\left(\text{a}\right) & \left(\text{b}\right) & \left(\text{c}\right) & \left(\text{d}\right) \\ \left(\text{i}\right) & \left(\text{ii}\right) & \left(\text{iv}\right) & \left(\text{iii}\right)\end{cases}
  3. C{(a)(b)(c)(d)(iii)(ii)(i)(iv)\begin{cases}\left(\text{a}\right) & \left(\text{b}\right) & \left(\text{c}\right) & \left(\text{d}\right) \\ \left(\text{iii}\right) & \left(\text{ii}\right) & \left(\text{i}\right) & \left(\text{iv}\right)\end{cases}
  4. D{(a)(b)(c)(d)(i)(ii)(iii)(iv)\begin{cases}\left(\text{a}\right) & \left(\text{b}\right) & \left(\text{c}\right) & \left(\text{d}\right) \\ \left(\text{i}\right) & \left(\text{ii}\right) & \left(\text{iii}\right) & \left(\text{iv}\right)\end{cases}

Correct answer

D. {(a)(b)(c)(d)(i)(ii)(iii)(iv)\begin{cases}\left(\text{a}\right) & \left(\text{b}\right) & \left(\text{c}\right) & \left(\text{d}\right) \\ \left(\text{i}\right) & \left(\text{ii}\right) & \left(\text{iii}\right) & \left(\text{iv}\right)\end{cases}

Step-by-step solution

Infrared →\toMuscular treatment
