Iv the image formed by a mirror is laterally inverted. Plane mirrors and image formation in plane mirrors if the reflecting surface of the mirror is flat then we call this type of mirror as plane mirrors.
Mirror formula helps us to find.
Plane mirror image formula. Substituting the different values of angles between two inclined mirrors we can tabulate the answer as follows. Locating an image in a plane mirror. The formula to find the number of images n formed between two plane mirrors inclined at angle between them is as follows.
Characteristics of images mirrors when a ray of light falls on a surface then it can undergo one of the following three phenomena reflection refraction or absorption. Here is the list of characteristics of an image formed by a plane mirror. Given picture below shows how we can find the image of a point in plane mirrors.
When it falls on a normal surface than most of the light gets absorbed. And is written. Image distance which is represented as v.
Now that all these conventions are clear. Let us know move on the mirror formula. If we measure distances from the mirror then the object and image are in opposite directions so for a plane mirror the object and image distances should have the opposite signs.
Iii a virtual and erect image is formed. Applying this to triangles pab and qab in and using basic geometry shows that they are congruent triangles. We have to see the rays coming from the object to see it.
This means that the distance pb from the object to the mirror is the same as the distance bq from the mirror to the image. Focal length which is represented as f. The law of reflection tells us that the angle of incidence is the same as the angle of reflection.
Angle between the two mirrors number of images formed n 45. I the size of the image is the same as the size of the object. Ii the distance of the object in front of the mirror is equal to the distance of the image behind the mirror.
Object distance which is represented as u. Learn reflection of light by plane mirror here. Light always has regular reflection on plane mirrors.
