Q. No.In Young's double-slit experiment, the source is white light. One of the holes is covered by a red filter and another by a blue filter. In this case:
| 1. | there shall be alternate interference patterns of red and blue. |
| 2. | there shall be an interference pattern for red distinct from that for blue. |
| 3. | there shall be no interference fringes. |
| 4. | there shall be an interference pattern for red mixing with one for blue. |

The figure shows a standard two-slit arrangement with slits \(S_1, S_2. P_1, P_2\) are the two minima points on either side of \(P\) as shown in the figure.
At \(P_2\) on the screen, there is a hole and behind \(P_2\) is a second \(2\text-\)slit arrangement with slits \(S_3, S_4\) and a second screen behind them.
| 1. | There would be no interference pattern on the second screen but it would be lighted. |
| 2. | The second screen would be totally dark. |
| 3. | There would be a single bright point on the second screen. |
| 4. | There would be a regular two-slit pattern on the second screen. |

Two Sources \(S_1\) and \(S_2 \) of intensity \(I_1\) and \(I_2\) are in front of a screen [Fig.(a)]. The pattern of intensity distribution seen in the central portion is given by Fig.(b).
In this case, which of the following statements are true?
| (a) | \(S_1\) and \(S_2\) have the same intensities. |
| (b) | \(S_1\) and \(S_2\) have a constant phase difference. |
| (c) | \(S_1\) and \(S_2\) have the same phase. |
| (d) | \(S_1\) and \(S_2\) have the same wavelength. |
Choose the correct option:
| 1. | (a), (b), (c) | 2. | (a), (b), (d) |
| 3. | (b), (c), (d) | 4. | (c), (d) |

Figure 10.2 shows a standard two slit arrangement with slits \(S_1, S_2. P_1, P_2\) are the two minima points on either side of P (Fig. 10.2). At \(P_2\) on the screen, there is a hole and behind \(P_2\) is a second 2- slit arrangement with slits \(S_3, S_4\) and a second screen behind them.
1. There would be no interference pattern on the second screen but it would be lighted.
2. The second screen would be totally dark.
3. There would be a single bright point on the second screen.
4. There would be a regular two slit pattern on the second screen.
