Answer» Answer:-━━━━━━━━━━━━━━━━━━━━━━━━━━ Ans 1:- Diffused or irregular reflection occurs when we are reading a newspaper. Ans 2:- Hypermetropia or LONG SIGHTEDNESS (Inability) are the names of the defect the eye is suffering from, when we cannot see a NEARBY object clearly. Ans 3:- A phenomena of obtaining many images by employing two or more mirrors is called multiple reflection. Ans 4:- The number of images formed by two adjacentmplane mirrors depends on the angle between the mirror. If two mirrors are inclined at an angle θ to each other then N (no. of images) = 360/θ-1. Ans 5:- It is known as cylindrical power; the eye cannot focus on VERTICAL and horizontal lines properly is called astigmatism. Ans 6:- The mirror image is known as upright image because it forms an erect image. ━━━━━━━━━━━━━━━━━━━━━━━━━━ |
