Lens Applications

Question 1

How do you view a real image on converging lens

Answer 1

To view a real image, first, the object cannot be on or beyond F. Then you will have to hold a piece of paper to where the image may be (on the opposite side of the lens) to see it.

Question 1

Why are converging lenses used for cameras rather than diverging lenses.

Answer 1

Converging lenses are used so that they can focus all the rays onto a singular point.

Question 2

How do you view a virtual image on a converging lens

Answer 2

First, have the object be in front of F as the image will refract, and then have its light rays traced back, appearing to be on the same side as the object, so get a piece of paper and move it in front of the F.
