What is an example of a concave mirror?
The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc.
What is concave mirror with diagram?
As the parallel rays coming from the object converge at the principal focus, F of a concave mirror; after reflection through it. Therefore, when the object is at infinity the image will form at F. Object at Infinity. Properties of the image formed: Point-sized image, highly diminished in size, Real and inverted image.
How many ray diagrams are there in concave mirror?
The intersection of these two rays after reflection gives the position of the image of the object. For a concave mirror any of the following four ray diagrams can be used for locating the image formed: a) A ray parallel to the principal axis, after reflection, will pass through the principal focus of a concave mirror.
Which mirror is used in ray diagram?
Summary Of Convex Mirror Ray Diagram
| Object Position | Image Position | Output Image |
|---|---|---|
| At Infinity | At the focus F, behind the mirror | Virtual and Erect |
| Between Infinity and the Pole | Between P and F, behind the mirror | Virtual and Erect |
How do you find the image in a concave mirror?
When the object is located at a location beyond the focal point, the image will always be located somewhere on the opposite side of the mirror. Regardless of exactly where in front of F the object is located, the image will always be located behind the mirror. In this case, the image will be an upright image.
What are the ray diagrams for convex mirror?
The method of drawing ray diagrams for convex mirrors is described below.
- Pick a point on the top of the object and draw two incident rays traveling towards the mirror.
- Once these incident rays strike the mirror, reflect them according to the two rules of reflection for convex mirrors.
