CBSE Class 12 Physics 2023 Delhi Set 2 Paper

Question : 2 of 11

Marks: +1, -0

Choose the correct option related to wavelengths

(

\lambda

) of different parts of electromagnetic spectrum.

$\lambda_{\;\text{x-rays }\;} < \lambda_{\;\text{micro waves }\;} < \lambda_{\;\text{radio waves }\;} < \lambda_{\;\text{visible }\;}$
$\lambda_{\;\text{visible }\;}>\lambda_{x\;\text{-rays }\;}>\lambda_{\;\text{Tadio waves }\;}>\lambda_{\;\text{micro waves }\;}$
$\lambda_{\;\text{radio waves }\;}>\lambda_{\;\text{micro waves }\;}>\lambda_{\;\text{visible }\;}>\lambda_{x\;\text{-rays }\;}$
$λ_{\;\text "visible "\;}< λ_{\;\text "micro waves "\;}< λ_{\;\text "radio waves "\;}< λ_{\;\text "x-rays "\;}$

Solution: 👈: Video Solution

Wavelength of radio wave

>0.1\,\text{m}

Wavelength of microwave:

1\,\text{mm}-0.1\,\text{m}

Wavelength of visible light:

400\,\text{nm}-700\,\text{nm}

Wavelength of X-rays:

10^{-3}\,\text{nm}-1\,\text{nm}
