Refraction of light at curved surfaces.....do 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
