Which of the following is the correct arrangement of the electromagnetic spectrum in the increasing order of frequency?
1 Microwaves, infrared, radio waves, visible light, X-rays
2 Radio waves, microwaves, infrared, visible light, X-rays
3 X-rays, visible light, infrared, microwaves, radio waves
4 Microwaves, radio waves, infrared, visible light, X-rays
Explanation:
B | Electromagnetic wave \lt br> (EM) | Frequency | | :--- | :--- | | Gamma rays | $10^{20}$ | | X-rays | $10^{19}-10^{16}$ | | UV-rays | $10^{16}-10^{14}$ | | IR | $10^{14}-10^{12}$ | | Microwaves | $10^{11}-10^9$ | | Radio | $10^9-10^4$ | So, option (b) is the correct increasing order of frequency.

Assertion (A): The colour of radiation does not change on passing through different medium. Reason (R): The media do not absorb or emit colours.
1 Both $\mathrm{A}$ and $\mathrm{R}$ are true and $\mathrm{R}$ is a correct explanation for $\mathrm{A}$
2 Both $\mathrm{A}$ and $\mathrm{R}$ are true but $\mathrm{R}$ is not a correct explanation for $\mathrm{A}$
3 $\mathrm{A}$ is true, $\mathrm{R}$ is false
4 A is false, $\mathrm{R}$ is true
Explanation:
C The colour of radiation does not change on passing through different medium. It is possible for light to be absorbed in a medium so, assertion is correct but reason is incorrect.
