Answer the following questions: (b) In viewing through a magnifying glass, one usually positions one’s eyes very close to the lens. Does angular magnification change if the eye is moved back? |
| Answer» Solution :(b) Yes, it DECREASES a little because the ANGLE SUBTENDED at the eye is then slightly less than the angle subtended at the LENS. The effect is negligible if the IMAGE is at a very large distance away. [Note: When the eye is separated from the lens, the angles subtended at the eye by the first object and its image are not equal.] | |
