# How do you find the focal length of a convex mirror?

## How do you find the focal length of a convex mirror?

Since the object distance (d) and the image distance (d’), then the focal length can be calculated using the formula of the mirror : The radius of curvature of a convex mirror is twice the focal length of a convex mirror. The radius of curvature of the convex mirror is 12 meters.

## Why is the rearview mirror of a motorcycle convex in shape?

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.

What is the radius of curvature of the rear view mirror?

A convex mirror used for rear-view on an automobile has a radius of curvature of 3.00 m. If a bus is located at 5.00 m from this mirror, find the position, nature and size of the image

What is a convex mirror?

A convex mirror is a spherical reflecting surface, where the bulging side of the mirror faces the source of light. It is referred to as a diverging or a curved mirror. The image on a convex mirror is always virtual, diminished and upright.

An object is at a distance of 50 cm from the convex mirror, and its focal length is 23 cm. Image Distance (d i) = 1/ ((1/f) – (1/d o)) = 1/ ((1/23) – (1/50)) = 42.5926 cm. You can also calculate focal length, image and object distance alternatively with the other known values.

### What is the image formed in front of a concave mirror?

An object is kept in front of a concave mirror of focal length 20 cm. The image formed is three times the size of the object. Calculate the two possible distances of the object from the mirror. We are given a concave mirror. Also given the image formed is three times the size of the object.

### How far away from a converging lens is a 5 cm image?

An object 5 cm in length is held 25 cm away from a converging lens of focal length 10 cm. Draw the ray diagram and find the position, size and the nature of the image formed. Converging lens means a convex lens. As the distances given in the question are large, so we choose a scale of 1: 5, i.e., 1 cm represents 5 cm.

How do you find the distance of an object from a mirror?

Calculate the two possible distances of the object from the mirror. We are given a concave mirror. Also given the image formed is three times the size of the object. is the object distance measured from the left side of the mirror. Therefore, the two possible distance of objects from the mirror are 26.67 cm and 13.33 cm from the left side.

What is the radius of curvature of a concave mirror?

Consider a concave spherical mirror with a radius of curvature equal to 60.0 centimeters. An object 6.00 centimeters tall is placed along the axis of the mirror, 45.0 centimeters from the mirror. You
