During a daytime football game you notice that a player's reflective helmet forms an image of the Sun 4.7 cm behind the surface of the helmet. |
Part A What is the radius of curvature of the helmet, assuming it to be roughly spherical? Express your answer using two significant figures.
|
Homework Answers
Since the distance of sun from the helmet is huge as compared to the radius of curvature of helmet so do can be considered as infinite
Now when object is at infinity image is formed at focus hence f = 4.7 cm
So R = 2f = 9.4 cm
