A beam of light from a source \(L\) is incident normally on a plane mirror fixed at a certain distance \(x\) from the source. The beam is reflected back as a spot on a scale placed just above the source \(L.\) When the mirror is rotated through a small angle \(\theta,\) the spot of the light is found to move through a distance \(y\) on the scale. The angle \(\theta\) is given by:
| 1. | \(\dfrac{y}{x}\) | 2. | \(\dfrac{x}{2y}\) |
| 3. | \(\dfrac{x}{y}\) | 4. | \(\dfrac{y}{2x}\) |
