## How do you solve a concave mirror?

- The mirror formula is 1f=1v+1u.
- The magnification m is given by m=−vu.
- According to sign conventions, for a concave mirror, the focal length (f) is negative, the object distance (u) is negative, the image distance (v) is positive for a virtual image and negative for a real image.

### How do you solve a ray diagram problem?

Step-by-Step Procedure 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 convex mirrors.
- Locate and mark the image of the top of the object.

#### What is concave mirror answer?

Concave mirrors A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.

**What is the formula of concave lens?**

Magnification produced by Concave Lens

Types of lenses | Object distance (u) | m=hiho |
---|---|---|

Concave | – | |m|<1 |

Convex | – | |m|=1, when hi=ho, |m|<1, when hi1, when hi>ho |

**How do you solve a concave and convex mirror?**

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

## What is mirror formula and lens formula?

A lens is usually curved from either one or both surfaces. Mirror formula is 1/f = 1/v + 1/u. Lena formula is 1/f = 1/v – 1/u.

### 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.

#### What is mirror formula?

A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’. The mirror formula is applicable for both, plane mirrors and spherical mirrors (convex and concave mirrors).

**Does Hi Ho Di do?**

m = hi/ho = –di/do. In the above equations, do is the distance between the object and the center of the lens, di is the distance between the image and the center of the lens, ho is the object height, hi is the image height, and f is the focal length of the lens.

**How do you find the distance of a concave mirror?**

Multiply the two equations by the image distance (di): do = the object distance (positive if the object is in the front of the surface of the concave mirror that reflects light) di = the image distance (positive if the image in the front of the surface of the concave mirror that reflects light.

## Why is the radius of curvature of a concave mirror positive?

If the image is behind the mirror surface which reflecting light, where light does not pass through the image, then the image distance is negative (virtual image). The center of the curvature of the concave mirror is in the front of the mirror surface which reflects light. Therefore, the radius of curvature of the concave mirror is positive.

### Why is a convex mirror chosen as the rearview mirror?

The convex mirror is chosen as the rearview mirror of a motorcycle because the properties of the image produced by the mirror are… Based on the two figure above can concluded that the properties of the image are virtual, upright, minimized. 7. An object is 12 cm in front of a convex mirror with a radius of 6 cm. The properties of the image are…

#### What are the sign rules for a concave mirror?

The sign rules for the concave mirror. If the object is in the front of the mirror surface which reflects light, the object distance (do) is positive. If the image is in the front of the mirror surface which reflecting light, where light passes through the image, then the image distance (di) is positive (real image).
