Curvature= ?

1/r

Definition of focal length:

It is the distance from the centre of the lens to the focal point.

Focal point

Where light from a distance is brought to a focus by the lens.

Imagine wave and ray point of view of light passing through a lens

Back (Definition)

Lens power=

1/ focal length

Curvature leaving lens=?

Curvature of waves entering lens + curvature added by lens

What is v and u

U-distance from source to lens


V - distance from lens to image of source

What is curvature measured in

Diopter

1/f = ?

1/v- 1/u

What's the difference between the distance from lens to image and focal length

Focal length is constant

Magnification (2 equations)

Imagine height / object height or v/u
