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.

(c) Draw ray diagrams to obtain the image characteristics in each case.arrow_forwardA group of students is given two converging lenses. Lens A has a focal length of 12.5 cm, and lens B has a focal length of 50.0 cm. The diameter of each lens is 6.50 cm. The students are asked to construct a microscope from these lenses that has the same magnification as the telescope in Problem 80 if possible, and they have this discussion: Avi: These are the same lenses we used to make a telescope. So they wont work as a microscope. Microscopes are for looking at close objects; telescopes are for looking at far objects. Cameron: All you need for a microscope are two converging lenses. I think the difference from a telescope is just that the order of the lenses is switched. A microscope is just a backward telescope. Shannon: I think the order of the lenses doesnt matter because the magnification is inversely proportional to both focal lengths. I think we have to adjust the distance between the lenses. a. What do you think? b. If a microscope can be constructed with these two lenses, describe its design. What is the minimum separation of the lenses?
