You are watching: Can a plane mirror produce a real image


You only have to look as much as the nearest bathroom to find an instance of an image formed by a mirror. Images in a plane mirror are the very same size as the object, are located behind the mirror, and are oriented in the same direction as the thing (i.e., “upright”).

To understand exactly how this happens, think about (Figure). 2 rays arise from point P, to win the mirror, and reflect right into the observer’s eye. Keep in mind that we usage the regulation of have fun to construct the reflect rays. If the reflected rays are prolonged backward behind the winter (see dashed present in (Figure)), lock seem come originate from point Q. This is where the image of suggest P is located. If us repeat this procedure for point

Summary

A airplane mirror constantly forms a virtual picture (behind the mirror).The image and also object room the same distance native a flat mirror, the picture size is the very same as the object size, and also the picture is upright.
What space the differences in between real and also virtual images? How can you phone call (by looking) whether picture formed through a solitary lens or mirror is actual or virtual?


Virtual image cannot it is in projected ~ above a screen. Friend cannot differentiate a real picture from a virtual picture simply by judging from the image perceived with your eye.


Yes, you have the right to photograph a online image. For example, if you picture your reflection native a airplane mirror, you obtain a picture of a virtual image. The camera focuses the light the enters its lens to kind an image; even if it is the source of the light is a genuine object or a reflection from mirror (i.e., a digital image) does no matter.


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


Devise an plan of mirrors enabling you to watch the back of your head. What is the minimum variety of mirrors required for this task?


If you wish to watch your entire body in a flat mirror (from head to toe), just how tall should the mirror be? go its size count upon your street away native the mirror? administer a sketch.


The mirror must be fifty percent your size and its optimal edge need to be at 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 that they type an edge of 120. An object is inserted on the bisector in between the mirrors. Build a beam diagram as in (Figure) to present how plenty of images are formed.


Consider a pair of level mirrors that room positioned so the they type an angle of 60. An object is put on the bisector between the mirrors. Construct a ray diagram together in (Figure) to present how many images space formed.
