## What are 3 examples of concave mirrors?

- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.

## What is the formula of a concave mirror?

1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

## How can we solve the mirror problem?

- Step 1: Make a list of the known quantities given in the problem.
- Step 2: Determine if the unknown quantities require you to use the mirror equation, the magnification equation, or both.
- Step 3: Solve the needed equation(s) symbolically for the unknown quantities.

## Which type of image is formed by concave mirror?

Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.

## What is the formula of mirror?

Let’s explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.

## What is the distance of a concave mirror?

At what distance from a concave mirror focal length 10 cm should an object 2 cm long be placed in order to get an erect image 6 cm tall? To find: Distance of the object from the mirror, u . Thus, the distance of the object from the mirror u is -6.67 cm.

## What is the image distance in concave mirror?

According to sign conventions, for a concave mirror, the focal length is negative, the object distance is negative, the image distance is positive for a virtual image and negative for a real image.

## How do you find the location of an 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.

## How do you calculate the focal length of a concave mirror?

- 1f.
- 1f.
- Or 1f.
- Or f=uvuโv.
- F=R2.

## How do you derive a mirror formula?

The distance of the principal focus from the pole is called the focal length (f). There is a relationship between these three quantities given by the mirror formula which is expressed as 1v+1u=1f. This formula is valid in all situations for all spherical mirrors for all positions of the object.

## Do concave mirrors produce real images?

Concave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real—meaning that the image appears on the same side of the mirror as the object.

## Which image Cannot be obtained by a concave mirror?

the type of image that cannot be obtained by a concave mirror is virtual image.

## What are 10 uses of convex mirror?

- Convex Mirrors in ATMs. Convex mirrors are usually placed on top of the ATMs.
- Convex Mirrors as Rear-View Mirrors.
- Convex Mirrors in Parking Lots.
- Convex Mirrors for Security Purposes.
- Convex Mirrors inside Buildings & Offices.

## Which mirror gives real image?

Solution: Concave mirrors can form real images. Convex and plane mirrors always form virtual images.

## What are the properties of concave mirror?

Concave mirrors will form both real and virtual images. When the object is closer to the mirror, a virtual and magnified image is formed. When the object is further away from the mirror, a real and diminished image is formed.

## Which mirror used in cars?

Convex mirror The side mirrors of the car and the rear view mirror of a car are made up of convex mirrors. This is because the image formed by a convex mirror is diminished and erect image, thus it provides a larger field of view.

## What is V in concave mirror?

The distance between the image and the pole of the mirror is called Image distance(v).

## How is image distance calculated?

## What is the distance of the image from the mirror?

The image distance always equals the object distance. The size of the image is the same as the object (the mirror does not magnify the image).

## When an object is placed 20 cm from a concave mirror?

When an object is placed 20 cm from a concave mirror, a real image magnified three times is formed.

## What is the distance of a concave mirror of focal length 10cm?

Answer. So the object should be placed at a distance of 6.7 cm from the pole of the concave mirror (on the left, in front of the mirror).

## What is the distance from a concave mirror to focal length 25?

Answer : 50 cm away.

## What is the formula of height of image in mirror?

Magnification Equation: The magnification equation for mirrors relates the magnification index to the heights of the object and the image as well as to the distance between the mirror and the object and image. The magnification equation states that m=hiho=โdido m = h i h o = โ d i d o .

## Is height of image in concave lens positive or negative?

The real image is always formed as inverted, therefore, for real image height is taken as negative.
