PHXII10:WAVE OPTICS
367957
Which of the following process can be explained by Huygens law
1 Law of reflection
2 Snell’s law
3 Polarisation
4 Both 1 & 2
Explanation:
Conceptual Question
PHXII10:WAVE OPTICS
367958
Wave front means
1 All particles have opposite phase of vibrations
2 All particles in it have same phase
3 Few particles are in same phase, rest are in opposite phase
4 None of these
Explanation:
Wave front is the locus of all the particles which vibrates in the same phase.
PHXII10:WAVE OPTICS
367959
Figure, shows wave fronts in still liquid, moving in the direction of the arrow towards the interface \(P Q\) between a rarer region and a denser region. Which of the lines shown may represent one of the wave fronts in the denser region?
1 I
2 II
3 III
4 IV
Explanation:
The incident and redfracted wavefronts are shown in the figure. So option (1) is correct.
PHXII10:WAVE OPTICS

By Huygen’s wave theory of light, we cannot explain the phenomenon of
1 Photoelectric effect
2 Interference
3 Polarisation
4 Diffraction
Explanation:
Huygen’s wave theory fails to explain the particle nature of light (photoelectric effect).
