You are watching: What is true about real images


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

To understand just how this happens, consider (Figure). 2 rays arise from point P, win the mirror, and reflect into the observer’s eye. Note that we use the regulation of enjoy to build the reflected rays. If the reflected rays are expanded backward behind the mirror (see dashed present in (Figure)), they seem to originate from allude Q. This is where the image of suggest P is located. If we repeat this procedure for allude

Summary

A airplane mirror always forms a virtual picture (behind the mirror).The image and object are the same distance indigenous a level mirror, the photo size is the exact same as the thing size, and the image is upright.
What space the differences between real and also virtual images? How have the right to you call (by looking) whether picture formed by a solitary lens or winter is actual or virtual?


Virtual image cannot it is in projected top top a screen. You cannot identify a real photo from a virtual image simply by judging from the photo perceived with your eye.


Yes, you have the right to photograph a virtual image. For example, if you photo your reflection indigenous a airplane mirror, you acquire a picture of a virtual image. The camera focuses the light that enters the lens to kind an image; whether the resource of the light is a genuine object or a have fun from mirror (i.e., a virtual image) does no matter.


No, you have the right to see the real image the same method you can see the virtual image. The retina of her eye successfully serves together a screen.


Devise an setup of mirrors allowing you to watch the earlier of her head. What is the minimum variety of mirrors essential for this task?


If you great to check out your whole body in a flat mirror (from head come toe), just how tall need to the winter be? go its size count upon your distance away native the mirror? provide a sketch.


The mirror must be fifty percent your size and also its top edge must be in ~ the level of your eyes. The dimension does not count on your street from the mirror.


Consider a pair of flat mirrors that are positioned so that they type an angle of 120. Things is inserted on the bisector in between the mirrors. Construct a beam diagram as in (Figure) to show how numerous images room formed.


Consider a pair of flat mirrors that room positioned so that they form an angle of 60. An object is inserted on the bisector in between the mirrors. Build a ray diagram together in (Figure) to show how numerous images are formed.
