Refraction of light at curved surfaces - do you know?

Refraction of light at curved you know?

How do you differentiate lens and spherical mirror?

Differentiate focal length and Focus?

Whether pole and optic centre denote same or different?

Differentiate centre of curvature and Radius of curvature?

Can you Identify different types of lenses?

Differentiate beam and ray

Factors effecting focal length of lens

Draw converging beam and diverging beam

What do you term the effective width of a lens through which refraction takes place?

Write lens formula and mirror formula

When do you say an image is magnified or enlarged?

Can you draw ray diagrams for convex and concave lenses?

Can you say convex lens acts both diverging and converging lens...explain
