Q. No.The main difference between the phenomena of interference and diffraction is that:
| 1. | diffraction is caused by reflected waves from a source whereas interference is caused due to the refraction of waves from a source. |
| 2. | diffraction is caused due to the interaction of waves derived from the same source, whereas interference is the bending of light from the same wavefront. |
| 3. | diffraction is caused due to the interaction of light from the same wavefront, whereas the interference is the interaction of two waves derived from the same source. |
| 4. | diffraction is caused due to the interaction of light from the same wavefront whereas interference is the interaction of waves from two isolated sources. |

In a double-slit experiment, the two slits are \(1~\text{mm}\) apart and the screen is placed \(1~\text m\) away. Monochromatic light of wavelength \(500~\text{nm}\) is used. What will be the width of each slit for obtaining ten maxima of double-slit within the central maxima of a single-slit pattern?
| 1. | \(0.2~\text{mm}\) | 2. | \(0.1~\text{mm}\) |
| 3. | \(0.5~\text{mm}\) | 4. | \(0.02~\text{mm}\) |
