Given below are two statements:
| Assertion (A): | The formula connecting u, v and f for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature. |
| Reason (R): | Laws of reflection are strictly valid for plane surfaces, but not for large spherical mirrors. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |

Suppose that the lower half of the concave mirror’s reflecting surface in the given figure is covered with an opaque (non-reflective) material. What effect will this have on the image of an object placed in front of the mirror?
| 1. | the image will show only half of the object |
| 2. | the image will show the whole of the object |
| 3. | the intensity of the image will be low |
| 4. | both (2) and (3) |

A mobile phone lies along the principal axis of a concave mirror, as shown in the figure. Then,
| 1. | the magnification is not uniform due to the length of the object along the principal axis. |
| 2. | the distortion of the image depends on the location of the phone with respect to the mirror. |
| 3. | both (1) and (2) |
| 4. | none of these |
