Q. No.Two sources, \(S_1\) and \(S_2,\) separated by a distance \(d,\) interfere by sending light waves along the line \(S_1S_2.\) The two sources vibrate in phase with each other, and the wavelength of light is \(\lambda.\) For which value of \(d\) do the two sources produce a maximum (along \(S_1S_2\))?
| 1. | \(\Large\frac{3\lambda}{2}\) | 2. | \(\Large\frac{5\lambda}{4}\) |
| 3. | \(6\lambda\) | 4. | \(\Large\frac{2\lambda}{3}\) |

Two waves from coherent sources meet at a point in a phase difference of \(\phi\) and path difference \(\Delta x.\) Both waves have same intensities \(I_0.\) Based on this information, match Column-I and Column-II.
| Column-I | Column-II | ||
| (a) | If \({\Delta x}=\dfrac{\lambda}{3}\) | (p) | resultant intensity will be \(3I_0\) |
| (b) | If \(\phi = 60^{\circ}\) | (q) | resultant intensity will be \(I_0\) |
| (c) | If \({\Delta x}=\dfrac{\lambda}{4}\) | (r) | resultant intensity will be zero |
| (d) | If \(\phi = 90^{\circ}\) | (s) | resultant intensity will be \(2I_0\) |
| 1. | a(q), b(p), c(s), d(s) |
| 2. | a(s), b(p), c(s), d(q) |
| 3. | a(q), b(s), c(s), d(p) |
| 4. | a(s), b(r), c(q), d(r) |
