Question

F - principal focus f - focal length C - optical centre pls, can someone give me names of other terms under the topic "LENSES"? hopefully using a diagram, pls!! 100 points, do not spam

Answer 1

Answer:

The focal point of a convex lens is the point where light rays parallel to the axis are brought to a point. The distance from the lens to this point is called the focal length of the lens.

Answer 2

ʜᴇʟʟᴏ!!!!

ʟᴇɴSᴇS,

A piece of transparent substance, usually glass, having two opposite surfaces either both curved or one curved and one plane, used in an optical device in changing the convergence of light rays, as for magnification, or in correcting defects of vision. There are two main types of lenses, known as convex (or converging) and concave (or diverging).

ᴘᴀʀᴛs ᴏғ ʟᴇɴsᴇs,

• Principle focus
• Centre of curvature
• Radius of curvature
• Principal axis
