Question

what is the difference between mirror and lens

Answer 1

• Mirrors are devices which are based on the principle of reflection whereas lenses are devices which are based on the theory of refraction.

• Material other than glass or clear plastic is required to manufacture mirrors, whereas lenses only require glass or clear plastic.

• A perfect mirror reflects 100% of light incident on it from the silvered surface. A perfect lens refracts 100% incident on it.

• There are only three main types of mirrors, whereas there are six main types of lenses.

Answer 2

A lens permits light to pass through it with a deflection specified by the refraction index of the material and wavelength of light, a mirror reflects light away from it at an angle that's a function of the angle of incidence of the light.
