Question

Chapter 41, Problem 1PLA

To determine

Whether the following statements about lenses are true or false and mark them.

Expert Solution & Answer

Answer to Problem 1PLA

Statement a: False

Statement b: False

Statement c: False

Statement d: False

Explanation of Solution

There are mainly two types of lens, converging lens and diverging lens.

The rays brought together to a point called focal length when a light beam of parallel rays incident on a converging lens. The focal point of the converging lens is always positive.

The rays diverges when a light beam of parallel rays incident on a diverging lens. The focal point of the diverging lens is always negative.

Conclusion:

(a) The parallel rays converge upon incident on a converging lens and its focal point is positive. Thus, statement (a) is false.
(b) When the path of the diverging light rays is traced backwards, they appear to come from a point called focal point. Thus, statement (b) is false.
(c) A double convex lens does not have a negative focal length. Thus, statement (c) is false.
(d) The focal point of the converging lens is always positive and the focal point of the diverging lens is always negative. Therefore, statement (d) is false.
