Chapter 9: Problem 35

Distinguish converging lenses from diverging lenses, and give examples of each type.

Short Answer

Expert verified
Answer: Converging lenses are lenses that cause parallel light rays to converge or focus at a single point, and they are thicker in the center and thinner at the edges. Examples of converging lenses include magnifying glasses, camera lenses, and eyeglasses for farsighted individuals. On the other hand, diverging lenses cause parallel light rays to spread apart or diverge, and they are thinner in the center and thicker at the edges. Examples of diverging lenses include eyeglasses for nearsighted individuals, glasses for minimizing peripheral vision distortion, and some types of projector lenses.

Step by step solution

01

Definition of Converging Lenses

Converging lenses are lenses that cause parallel light rays to converge or focus at a single point. These lenses are thicker in the center and thinner at the edges. They are also known as positive or convex lenses.
02

Examples of Converging Lenses

Examples of converging lenses include magnifying glasses, camera lenses, and eyeglasses for farsighted individuals.
03

Definition of Diverging Lenses

Diverging lenses are lenses that cause parallel light rays to spread apart or diverge, as they pass through the lens. These lenses are thinner in the center and thicker at the edges. They are also known as negative or concave lenses.
04

Examples of Diverging Lenses

Examples of diverging lenses include eyeglasses for nearsighted individuals, glasses for minimizing peripheral vision distortion, and some types of projector lenses.

Most popular questions from this chapter

A convex lens forms a clear, focused image of some small, fixed object on a screen. If the screen is moved closer to the lens, will the lens have to be (a) moved closer to the object, (b) moved farther from the object, or (c) left at the same location to produce a clear image on the screen at its new location? Explain your answer.

Explain why images seen through flat, smooth, uniform, plate-glass windows are undistorted.

Why are the Doppler effect and diffraction not as commonly experienced with light as they are with sound?

Describe how the path of a ray is deviated as it passes (at an angle) from one medium into a second medium in which the speed of light is lower. Contrast this with the case when the speed of light in the second medium is higher.

Distinguish between specular reflection and diffuse reflection.
