 PLEASE TELL THE DIFFERRENCE BETWEEN CONVEX AND CONCAVE MIRROR

AND

VIRTUAL AND REAL IMAGE

Concave mirror:

The reflecting surface of the concave mirror is bulged inwards.

Concave mirror produces real and inverted images (except when the object is placed between pole and focus. When the object is placed between F and P, concave mirror produces virtual and erect image). The image formed by the concave mirror may be enlarged or diminished, according to the position of the object.

Convex mirror:

The reflecting surface of the convex mirror is bulged outwards.

Convex mirror always produces virtual and erect images. The image formed by the convex mirror will be always diminished.

_______  _________

A Virtual Image is said to form where the light rays appear to meet but do not do so. We however can see a virtual image like the reflection in a plane bathroom mirror. It is supposed to be formed behind the mirror/lens. Common example of virtual image would be the reflection in a plane mirror.

A Real image is formed by actual meeting of light rays after hitting the optical system. In order to see a real image we require a viewing screen on which the light rays fall and form an image. So, we can indeed see real images but a screen in crucial for that. A very common example would be the image formed on a cinema screen

Concave mirror diverges the beam of light incident on it hence it is called diverging mirror
while convex mirror converges the beam of light incident on it hence it is called converging mirror

Shapes

-Concave mirror is curved inwards.
-Convex mirror is curved outwards.

Focal Point

It is the point where the beam of ray intersects after reflection or tend to intersect. It is located on the principal axis.
-The focal point of concave mirror is in front of the mirror.
-The focal point of convex mirror is behind the mirror

Image

-In convex mirror the image is always virtual, upright and smaller than the object
-In case of concave mirror different types of images are formed on different location of the object. The image is upside down (inverted) and far away but if we bring the object close to the mirror then image will be larger and upright.

Uses

Convex mirrors are used in cars (as passenger-side mirror since they provide upright and wide view), they are also used in camera phones, for safety measures there are also used in roads and driveways

Besides these convex mirrors are found in many hospitals, schools etc. as hallway safety mirror.

Concave mirrors are used in telescope. These are also used as make up and shaving mirrors since these provide larger images.
besides these concave mirrors are used by dentists and also used in headlights of cars, solar devices, satellite dishes e

If the reflecting surface of a spherical
mirror is concave, it is called a concave
mirror.
If the reflecting surface is convex,
then it is a convex mirror.
 
A concave mirror can form a real and inverted image. When the object is
placed very close to the mirror, the image formed is virtual, erect and
magnified.
Image formed by a convex mirror is erect, virtual and smaller in size
than the object.
 
 
An image which can be obtained on a screen is called a real image.
„An image which cannot be obtained on a screen is called a virtual image.

Real-It can be formed on the screen
Light rays actually meet after refraction
Virtual-It cannot be formed on screen
Light rays do not meet after refractio
