HOW IS lens important for camera?
A camera lens is an optical lens and also known as photographic objective or photographic lens. The good lens allows enough light to pass through it and also focus the light properly on the sensor. Quality of an image is so dependent on the camera lens.
What does a lens do?
lens, in optics, piece of glass or other transparent substance that is used to form an image of an object by focusing rays of light from the object.
What is the power of lens?
The power of a lens is defined as the reciprocal of the focal length. Converging (convex ) lenses have positive focal lengths, so they also have positive power values. Diverging (concave ) lenses have negative focal lengths, so they also have negative power values.
Do lenses reflect light?
Lenses serve to refract light at each boundary. As a ray of light enters a lens, it is refracted; and as the same ray of light exits the lens, it is refracted again.

WHAT IS lens formula?
Lens equation or lens formula is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, Lens Formula – 1/u + 1/v = 1/f. where.
What is the capacity of lens?
Definition: It is the capacity or the ability of a lens to deviate (converge or diverge) the path of rays passing through it. A lens producing more converging or more diverging, is said to have more power. The unit for power is dioptre (D). The shorter the focal length, the greater the power.
