1. When a light wave enters into a medium of different optical density,
2. What principle is responsible for light spreading as it passes through a narrow slit?
3. One beam of coherent light travels path P1 in arriving at point Q and another coherent beam travels path P2 in arriving at the same point. If these two beams are to interfere destructively, the path difference P1 - P2 must be equal to
Two beams of coherent light travel different paths arriving at point P. If the maximum constructive interference is to occur at point P, the two beams must
7. An unpolarised light of intensity I0 is incident on a pair of nicols at an angle of 600 with each other. The intensity of light emerging from the pair is
Which one of the statements is correct?
How does making each of the double slits narrower affect the appearance of the fringes?
