An image is formed due to the ;ystem. 1e distance of this image from lens 2. 2f 011 10.0 points
A lens having a focal length 50 cm is used as
a simple magnifier.
What is the angular magnification obtained when the image is formed at the normal near
point (25 cm)? 012 10.0 points
A shallow pool of a liquid 6.1 m deep is not
the depth one expects when viewed from over-
head. The index of refraction of the liquid is
1.25.
How deep does it appear to be?
Answer in units of cm. 013 10.0 points
