The size of an obstacle in order to observe diffraction of light must be
1 of any order
2 of the order of wavelength
3 central band is narrower
4 central band is wider
Explanation:
: For pronounced diffraction of waves, the size of the obstacle or aperture should be of order of the wavelength of the light used.

The diffraction effect can be observed in
1 only sound waves
2 only light waves
3 only ultrasonic waves
4 sound as well as light waves
Explanation:
: Diffraction is a phenomenon that occurs when waves encounter on obstacle or opening that is comparable in size etc their wavelength. This causes the waves to bend and spread out, producing a pattern of interference and diffraction and diffraction effect can be observed in both sound and light waves.

In order to see diffraction the thickness of the film is
1 \(100 \AA\)
2 \(10,000 \AA\)
3 \(1 \mathrm{~mm}\)
4 \(1 \mathrm{~cm}\)
Explanation:
: The thickness of a film can affect the diffraction pattern that is produced when light passes through it. Film thickness must be on the order of the wavelength of \(10000 \AA\).

For fraunhoffer diffraction to occur
1 Light source should be at infinity
2 Both source and screen should be at infinity
3 Only the source should be at finite distance
4 Both source and screen should be at finite distance
Explanation:
: Fraunhoffer diffraction is a experimental setup and it is occur when both source and screen at infinity.
