Question

A small bulb is placed in front of a convex lens Suppose that the bulb is placed as shown. Using all three principal rays, draw an accurate ray diagram to determine the location of the image. Label the image location. Small bulb b. Repeat part a for the case shown at right, in which the bulb is farther from the lens. Small bulb bangladov Lens c. Suppose that in each case above you were to place a small paper screen at the image location. What you would see on the screen in each case? Imagine that the room is dark except for the small bulb. d. The light bulb is placed at one focal point of the lens as shown at right. Small bulbs at focal point Draw at least five rays from the bulb that pass through the lens. Lens Where is the image located in this case? Explain. (Hint: How are the rays that have passed through the lens oriented? From where do these rays appear to have come?)

Answer 1

The solution of the problem is given below

solution Lens > image 3 o 1, 2, 3 says and I object (Bully)

Date I o object, I mage, 1,2,3 rays No will be le case (b) case seen on the screen only as the unege is real in this > 2 The rays enerzug out of lens are permleil to each other, therefore the funil mnoge will be formed at infinity of very for from the lens.
