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 |

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. |
