A physics lab homework focusing on the topic of light. It includes various questions and tasks related to the formation of images using lenses, the effect of object position on image formation, and the variation of light intensity. Students are expected to draw rays, explain image formation, and observe the effects of blocking parts of the setup.

(a) In the figure above, draw in three principle rays which originate at the object and end on the image. (b) Will a real image formed by a convex lens always be inverted? Explain.
Describe what happens in each of the following cases, and explain in terms of the observations you made in this lab of the light rays leaving the top and bottom of the arrow:
(c) What happens to the image when the top half of the lens is blocked by a card? Explain.
(d) What happens to the image when the top half of the arrow is covered? Explain.

(e) What happens to the image when the object is moved a bit toward the right? Ex- plain.
(f) What happens to the image when the object is moved to the right very close to the lens? Explain.
(g) What happens to the image when the object is moved a bit toward the left? Explain.
(h) What happens to the image when the lens is removed? Explain.
(a) Describe how the light intensity varies as you move further and further away from the light bulb.
(b) If the ping pong ball is in a lighted room, would there be any difference from your answer to (a) in the way the light intensity varies as you move further and further away from the ball? Explain your answer.
