You are watching: Which describes an image that a plane mirror can make?


You only need to look as much as the nearest bathroom come find an example of an image formed through a mirror. Images in a aircraft mirror room the same size as the object, are located behind the mirror, and are oriented in the same direction together the thing (i.e., “upright”).

To understand just how this happens, consider (Figure). Two rays arise from allude P, strike the mirror, and also reflect into the observer’s eye. Keep in mind that we usage the regulation of enjoy to build the reflected rays. If the reflected rays are extended backward behind the winter (see dashed lines in (Figure)), castle seem to originate from point Q. This is wherein the photo of suggest P is located. If we repeat this procedure for allude

Summary

A airplane mirror always forms a virtual image (behind the mirror).The image and object room the very same distance from a flat mirror, the picture size is the exact same as the object size, and also the picture is upright.
What room the differences between real and virtual images? How deserve to you tell (by looking) whether picture formed through a single lens or winter is genuine or virtual?


Virtual photo cannot it is in projected ~ above a screen. Girlfriend cannot identify a real picture from a virtual picture simply by judging from the photo perceived through your eye.


Yes, you can photograph a digital image. For example, if you photo your reflection native a plane mirror, you acquire a photograph of a virtual image. The camera concentrates the light the enters that is lens to kind an image; whether the source of the light is a genuine object or a reflection from winter (i.e., a online image) does not matter.


No, you have the right to see the real photo the same way you deserve to see the digital image. The retina of her eye effectively serves as a screen.


Devise an arrangement of mirrors permitting you to see the back of her head. What is the minimum number of mirrors essential for this task?


If you wish to see your whole body in a level mirror (from head come toe), how tall must the mirror be? does its size depend upon your street away from the mirror? administer a sketch.


The mirror need to be half your size and its height edge must be in ~ the level of your eyes. The size does not depend on your distance from the mirror.


Consider a pair of level mirrors that are positioned so the they type an edge of 120. An item is placed on the bisector between the mirrors. Construct a ray diagram together in (Figure) to display how numerous images space formed.


Consider a pair of level mirrors that are positioned so the they form an edge of 60. Things is put on the bisector in between the mirrors. Build a beam diagram together in (Figure) to present how countless images space formed.
