What is the difference between concave and convex mirror with diagram?
What is the difference between Concave and Convex mirror?
| Concave mirror | Convex mirror |
|---|---|
| It’s focus and centre of curvature lies in front of the motor | It’s focus and centre of curvature lies behind the mirror. |
| It is also called a converging mirror. | It is also called a diverging lens. |
How do you determine convex and concave sides?
Concave vs. Convex
- Concave describes shapes that curve inward, like an hourglass.
- Convex describes shapes that curve outward, like a football (or a rugby ball).
What is the ray diagram of convex mirror?
To summarise
| Position of the object | Position of the image | Nature of the image |
|---|---|---|
| At infinity | At the focus F, behind the mirror | Virtual and erect |
| Between infinity and the pole P of the mirror | Between P and F, behind the mirror | Virtual and erect |
How do you draw a ray diagram for a concave and convex 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 is a ray in 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 is the difference between convex and concave?
Concave means “hollowed out or rounded inward” and is easily remembered because these surfaces “cave” in. The opposite is convex meaning “curved or rounded outward.” Both words have been around for centuries but are often mixed up. Advice in mirror may be closer than it appears.
What is concave up and concave down?
Concavity relates to the rate of change of a function’s derivative. A function f is concave up (or upwards) where the derivative f′ is increasing. Similarly, f is concave down (or downwards) where the derivative f′ is decreasing (or equivalently, f′′f, start superscript, prime, prime, end superscript is negative).
What is the difference between convex and concave lens?
A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens.
What is concave and convex lens?
Lenses may be divided broadly into two main types: convex and concave. Lenses that are thicker at their centers than at their edges are convex, while those that are thicker around their edges are concave. A light beam passing through a convex lens is focused by the lens on a point on the other side of the lens.
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.
