What is called concave mirror?
Concave mirrors
A concave mirror, or
converging mirror

, they are called convex mirrors. (vex stands for bulging out).
Which is convex lens?
A convex lens is also known as a
converging lens
. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis. They can be identified by their shape which is relatively thick across the middle and thin at the upper and lower edges.
Which mirror is used in car?
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 the example of convex mirror?
The examples of convex mirrors are the
mirrors used as rear side mirrors of vehicles
, optical instruments, calling bell, etc.
What is V and U in physics mirror?
The distance between the object and the pole of the mirror is called the object distance(u). The
distance between the image and the pole of the mirror
is called Image distance(v).
What is plane mirror physics?
Definition:
The flat surface that produces an erect visual image of a real object where front and back are reversed
. plane mirror.
What is the other name for convex lens?
The another name of convex lens is
converging lens
.
What is the difference between concave and 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 a convex mirror Class 7?
A convex mirror generally
produces anerect and smaller image of the object
. Convex mirror produce virtual images of the objects spread over large area. Convex mirrors cannot produce real images.
Where is convex lens used?
Convex lenses are used in
microscopes, magnifying glasses and eyeglasses
. They are also used in the cameras to create real images of objects present at a distance.
Where are concave and convex mirrors used?
Concave mirror is used by dentist, solar furnace, reflector of a torch, etc.
Convex mirror is used in rear view mirrors
.
Which mirror is used in vehicles headlight?
A convex mirror
is used as a reflector in the head lights of a car.
What are shaving mirrors?
A shaving mirror is
a small, often round, mirror that can be moved out from a wall
, and which you use to see your reflection when you are shaving your face. The shaving mirror is next to the basin and is mounted on a retractable arm.
Which mirror is used in torch?
Concave mirror
is used as torch reflector.
How many cases are there in convex mirror?
So, there will only be
2 cases
.
What are the 2 cases of convex mirror?
- Rule 1:
- Rule 2:
- Rule 3:
- Rule 4:
- Case 1: When object is placed at Infinity.
- Case 2: When object is placed anywhere on the principal axis.
Which mirror is used by dentist?
A concave mirror
gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see.
What is concave mirror Class 10?
1)Concave Mirror:
A spherical mirror whose reflecting surface is curved inwards ie faces towards the centre of sphere
.
Is called converging mirror?
Concave mirror
is called a converging mirror because parallel rays of light fall on the mirror they converge at a point called focus. Convex mirror is called a diverging mirror because parallel rays of light fall on it they diverge after reflection.
What are 3 examples of concave mirrors?
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
What is concave and convex mirror Class 10?
Spherical mirrors whose inner side is reflecting are
called concave mirrors. Spherical mirrors whose outer side is reflecting are called convex mirrors. It’s focus and centre of curvature lies in front of the motor. It’s focus and centre of curvature lies behind the mirror.
What are the different types of concave mirror?
Simple Uses of Concave Mirrors
The two types of spherical mirrors are
concave and convex
. Each type reflects images in a different fashion. This is due to the curve of the mirror.
What are examples of concave?
The front side of a spoon is curved inwards. Such a surface is called concave.
The inside part of a bowl
is also an example of a concave surface. Concave mirrors are used in various medical practices.
What are 2 examples of a convex lens?
- Human Eye.
- Magnifying Glasses.
- Eyeglasses.
- Cameras.
- Telescopes.
- Microscopes.
- Projector.
- Multi-Junction Solar Cells.
What is convex lens in BYJU’s?
A convex lens is
a converging lens
. Therefore when parallel light rays pass through the lens, the refracted rays converge at one point, which is called the principal focus. The angle at which the rays of light enter the convex lens depends on the distance of the object from the lens.
Which lens is used in flashlight?
Concave lenses
are used on flashlights to magnify the light produced by the bulb. The light falls on the concave side of the lens, and the rays diverge on the other side, thereby increasing the apparent radius of the light source and providing a wider beam.
Which lens is used in telescope?
This type of telescope is called a refracting telescope. Most refracting telescopes use two main lenses. The largest lens is
called the objective lens
, and the smaller lens used for viewing is called the eyepiece lens.
Which mirror is used in telescope?
The major component of a reflecting telescope is the
concave mirror
. The concave mirror is known as a converging mirror because it converges a ray of light travelling from infinity, to its focal point.
Which mirror is used in solar cooker?
Note:
A plane mirror
can be used in a solar cooker but it cannot concentrate the rays at point as the concave mirror does. Thus, the maximum heat will not be achieved. A convex cannot be at all since it will diverge away the sun rays falling on it.
Which mirror is used in barber shop?
Complete step by step answer:
Commonly plane mirrors
used to see ourselves so, it is widely used in the barbershop, salon, and beauty parlor. For the purpose of using a plane mirror in shops to give a better view of hair from the front and back to the customers. A plane mirror always forms a virtual image.
