JEE MAIN - Physics (2024 - 4th April Evening Shift - No. 19)

Arrange the following in the ascending order of wavelength:

A. Gamma rays $$\left(\lambda_1\right)$$

B. $$x$$ - rays $$\left(\lambda_2\right)$$

C. Infrared waves $$\left(\lambda_3\right)$$

D. Microwaves $$\left(\lambda_4\right)$$

Choose the most appropriate answer from the options given below

$$\lambda_1<\lambda_2<\lambda_3<\lambda_4$$
$$\lambda_2<\lambda_1<\lambda_4<\lambda_3$$
$$\lambda_4<\lambda_3<\lambda_2<\lambda_1$$
$$\lambda_4<\lambda_3<\lambda_1<\lambda_2$$

Explanation

Wavelengths are as

Gamma rays $$<1 \mathrm{~nm}$$

x-ray < $$(1-10)$$ nm

Infrared $$<(700-10^5) \mathrm{~nm}$$

Microwave $$<(10^5-10^8) \mathrm{~nm}$$
