Question

Difference between convex mirror and concave mirror brainly

Answer 1

CONCAVE MIRROR :

• A spherical mirror whose reflecting surface is curved inwards is called a concave mirror.
• A parallel beam of light falling on this mirror converges at a point after reflection.
• It is also called a converging mirror.
• It has a real focus.
• The magnification of a concave mirror can be greater, equal or less than 1.
• These mirrors are used as reflectors in projectors, light-house headlights, searchlights, etc.

CONVEX MIRROR :

• A spherical mirror whose reflecting surface is curved outwards is called a convex mirror.
• A parallel beam of light falling on this mirror appears to diverge from a point after reflection.
• It is also called a diverging mirror.
• It has a virtual focus.
• The magnification of a convex mirror is always less than 1.
• These mirrors are used as rear-view mirrors in cars and motorcycles, as they enable the driver/rider to view the road and vehicles behind.

Answer 2

Differences between convex and concave mirror:

Convex mirror:

1. The reflecting surface is curved outward.

2. After reflection from the mirror the light rays diverge.

3. The image formed due to convex mirror is always virtual and diminished.

4. It is used as rear view mirror.

Concave mirror:

1. The reflecting surface curved inward.

2. After reflection from the mirror the light rays converge.

3. The image formed due to concave mirror is generally real and either diminished or magnified. But when an object placed between vertex and focus it is virtual.

4. It is used in car headlights.
