Assertion : No diffraction is produced i...

Assertion : No diffraction is produced in sound waves near a very small opening.
Reason : For diffraction to take place, the aperture of opening should be of same order as wavelength of waves.

A

If both, Assertion and Reason are true and the Reason is the correct explaination of the Assertion.

B

If both, Assertion and Reason are true but Reason is not a correct explaination of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Wavelength of sound is of the order of one metre , and size of opening is much smaller. Therefore, sound is not diffracted. Choice (a) is correct.

Assertion (A): Diffraction takes place with all types of waves. Reason (R): Diffraction is perceptible when the wavelength of the wave is comparable to the dimension of the diffracting device.

Assertion: Standard optical diffraction cannot be used for discrimination between different X-ray wavelengths. Reason: The grating spacing is not of the order of X-ray wavelengths.

Assertion: To observe diffraction of light the size of obstacle/aperture should be of the order of 10^-7m . Reason: 10^-7m is the order of wavelength of visible light.

Assertion: Out of radio waves and microwaves, the former undergoes more diffraction. Reason: Radio waves have greater frequency compared to microwaves.

Assertion : Doppler effect is not observed in case of supersonic waves. Reason : Waves produced by supersonic sources are shock waves which produce a sound.
