Short Answer

Expert verified
Question: Identify whether the following images are real or virtual: a) Image on the retina in a person's eye. b) Image one sees in a rearview mirror. c) Image one sees on a movie screen. d) Image one sees through a magnifying lens.

Step by step solution

01

Determine Image Type

In a person's eye, the light rays enter through the pupil and are focused by the lens onto the retina. The light rays actually converge at the retina, forming a real image. So, the image on the retina in a person's eye is a real image. #b) Image one sees in a rearview mirror.#
02

Determine Image Type

In a rearview mirror, which is a flat plane mirror, the light rays appear to come from behind the mirror but they don't actually converge; they only appear to converge at a point behind the mirror. Hence, the image one sees in a rearview mirror is a virtual image. #c) Image one sees on a movie screen.#
03

Determine Image Type

In a movie projector, the light rays from the projector lens are focused onto the screen, and the light rays converge to form the image on the screen. Thus, the image one sees on a movie screen is a real image. #d) Image one sees through a magnifying lens.#
04

Determine Image Type

When we look through a magnifying lens, it makes the light rays appear to diverge from a point behind the object being observed, creating a virtual image. So, the image one sees through a magnifying lens is a virtual image. In conclusion: a) Real image b) Virtual image c) Real image d) Virtual image

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 (i) moved closer to the object, (ii) moved farther from the object, or (iii) left at the same location to produce a clear image on the screen at its new location? Explain your answer.

What is chromatic aberration? How can it be remediated?

Suppose an explosion at a glass factory caused it to "rain" tiny spheres made of glass. Would the resulting rainbow be different from the normal one? If so, how might it be different and why?
