Two coherent sources of light interfere and produce fringe patterns on a screen. For the central maximum, the phase difference between the two waves will be:
1. | zero | 2. | \(\pi\) |
3. | \(\dfrac{3\pi}{2}\) | 4. | \(\dfrac{\pi}{2}\) |
1. | \(\dfrac{\sqrt{n}}{n+1}\) | 2. | \(\dfrac{2\sqrt{n}}{n+1}\) |
3. | \(\dfrac{\sqrt{n}}{(n+1)^2}\) | 4. | \(\dfrac{2\sqrt{n}}{(n+1)^2}\) |
Two periodic waves of intensities I1 and I2 pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities is:
1.
2.
