# Chosse the correct option relating wavelengths of different parts of electromagnetic wave spectrum:

Question:

Chosse the correct option relating wavelengths of different parts of electromagnetic wave spectrum:

1. (1) $\lambda_{\text {visible }}<\lambda_{\text {micro waves }}<\lambda_{\text {radio waves }}<\lambda_{x \text {-rays }}$

2. (2) $\lambda_{\text {radio waves }}>\lambda_{\text {micro waves }}>\lambda_{\text {visible }}>\lambda_{x \text {-rays }}$

3. (3) $\lambda_{x \text {-rays }}<\lambda_{\text {micro waves }}<\lambda_{\text {radio waves }}<\lambda_{\text {visible }}$

4. (4) $\lambda_{\text {visible }}>\lambda_{x \text {-rays }}>\lambda_{\text {radio waves }}>\lambda_{\text {micro waves }}$

Correct Option: , 2

Solution:

(2) The orderly arrangement of different parts of EM wave

in decreasing order of wavelength is as follows:

$\lambda_{\text {radiowaves }}>\lambda_{\text {microwaves }}>\lambda_{\text {visible }}>\lambda_{\text {X-rays }}$
