Question

Assertion (A): Out of Infrared and radio waves, the radio waves show more diffraction effect.

Reason (R): Radio waves have greater frequency than infrared waves.

Options

• If both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• If both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• If Assertion (A) is true but Reason (R) is false.

• If both Assertion (A) and Reason (R) are false.

Answer 1

If Assertion (A) is true but Reason (R) is false.

Explanation:

Radio waves diffract more diffraction than infrared waves due to the enhanced diffraction associated with longer wavelengths. Radio waves, measured in meters to kilometers, possess significantly bigger wavelengths than infrared waves, which are measured in micrometers. Additionally, radio waves, ranging from kilohertz to gigahertz, exhibit lower frequencies compared to infrared waves, which operate in terahertz. This inverse connection results in longer wavelengths for radio waves.
