PHXII10:WAVE OPTICS

In a diffraction (single slit experiment), slit is exposed by white light. The fringes surrounding the central fringe is
1 Yellow
2 Red
3 Green
4 Violet
Explanation:
The position of 1st maxima from the centre of the screen is \(y = \frac{{3\lambda D}}{a}\) \(y\,\alpha \;\lambda \) \({\lambda _v} - \) is the least wavelength. After the central maxima the violet colour fringe will be formed.

Bending of light wave at the sharp edges of an opaque obstacle is known as
1 Refraction
2 Reflection
3 Diffraction
4 Interference
Explanation:
Conceptual Question

The luminous border that surrounds the profile of a mountain just before sun rises behind it, is an example of
1 Dispersion
2 Total internal reflection
3 Interference
4 Diffraction
Explanation:
The luminous border that surrounds the profile of a mountain just before sun rises behind it due to the diffraction of light
PHXII10:WAVE OPTICS

Diffraction of sound waves is more evident than light waves in daily life because:
1 \({\lambda _{sound}} > {\lambda _{light}}\)
2 \({\lambda _{sound}} = {\lambda _{light}}\)
3 \({\lambda _{sound}} < {\lambda _{light}}\)
4 Sound waves are longitudinal but light waves are transverse.
