Chapter 25: Q21CQ (page 928)

Is it necessary to project a real image onto a screen for it to exist?

Short Answer

Expert verified

No, even without projection, an actual image exists.

Step by step solution

01

Define Geometric Optics

Geometrical optics, often known as ray optics, is an optics model that describes light propagation using rays. In geometric optics, a ray is an abstraction that can be used to approximate the routes along which light propagates under particular conditions.

02

Explanation

Yes, even in the absence of a screen, genuine images are produced. If a mirror is present, the true picture will serve as an object for the mirror and will be mirrored.

Therefore, No, even without projection, there is a real image.
