How do you draw a ray diagram for a concave mirror?
Step-by-Step Method for Drawing Ray Diagrams
- 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 concave mirrors.
- Mark the image of the top of the object.
What are the six ray diagrams of concave mirror?
To summarize
| Position of the object | Position of the image | Nature of the image |
|---|---|---|
| At C | At C | Real and inverted |
| Between C and F | Beyond C | Real and inverted |
| At F | At infinity | Real and inverted |
| Between P and F | Behind the mirror | Virtual and erect |
How many ray diagrams are there for 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.
What is a ray diagram?
A ray diagram is a diagram that traces the path that light takes in order for a person to view a point on the image of an object. On the diagram, rays (lines with arrows) are drawn for the incident ray and the reflected ray. Complex objects such as people are often represented by stick figures or arrows.
What are the ray rules for concave mirror?
Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.
What are ray diagrams?

How do you remember ray diagrams?
Expert Answer:
- Hi,
- The following points should be noted while drawing ray diagrams and solving numerical of light:
- 1) Note the position of object carefully,
- 2) Understand the rules of drawing a ray diagram as given in the text.
- 3) Use appropriate scale so that the size and distance of object and image fit on the paper.
What is the example of ray?
In geometry, a ray is a line with a single endpoint (or point of origin) that extends infinitely in one direction. An example of a ray is a sun ray in space; the sun is the endpoint, and the ray of light continues on indefinitely.
What are the 3 rules for ray diagrams?
Rules for drawing Ray Diagram in Lenses
- Rule 1 – Ray parallel to principal axis will pass through focus. For a convex lens ,
- Rule 2 – Ray passing through focus will become parallel to principal axis. For a convex lens,
- Rule 3 – Ray passing through Optical Center will emerge without deviation.
