Question

Assertion :We can hear around corners, but we cannot see around corners. Reason: Wavelength of sound in much greater than wavelength of light.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

First we need to understand diffraction, The bending of waves around corners or obstacles is called diffraction. Diffraction is noticeable when order of size of the obstacle is and size of the wavelength match. Sound waves have much longer wavelengths in comparison to light waves. that's why the diffraction of sound waves around a corner is noticeable and we can hear the sound around corners but can't see around corners
