Differentiate between convex mirror and concave mirror.

Convex mirror Concave mirror 1) A convex mirror diverges the light rays 1) A concave mirror converges the light rays 2) The spherical mirror in which the reflection of light takes place at the bulging surface (convex surface) is called convex mirror. 2) The spherical mirror in which the reflection of light takes place at a bent surface (concave surface) is called concave mirror. 3) The focal length is negative in a convex mirror 3) The focal length is positive in a concave mirror 4) The convex mirror produces only virtual images 4) Concave mirror produces both real and virtual images

Distinguish between real image and virtual image.

Real image Virtual image 1) Real image can be obtained on a screen. 1) Virtual images cannot be obtained on a screen. 2) A real image is formed when light rays coming from an object actually meet at a point after reflection from a mirror or refraction through a lens. 2) A virtual image is formed when light rays coming from an object only appear to meet at a point when produced backward after reflection from a mirror or refraction through a lens. 3) Real images are inverted. 3) Virtual images are erect.
