mirrors

Question 1

what is a spherical mirror?

Answer 1

such mirrors those whose reflecting surfaces are spherical are called spherical mirror?

Question 2

types of spherical mirrors?

Answer 2

concave and convex

Question 3

parts of the mirror?

Answer 3

1.pole
2.focus
3.principal axis
4.center of curvature
5.focal length
6.radius of curvature

Question 4

what is pole?

Answer 4

center of the reflecting surface of the curved surface is called pole.

Question 5

what is focus?

Answer 5

the point at the principal axis through which incident ray pass or appear to pass is called focus.

Question 6

what is principal axis?

Answer 6

the line passes through center of curvature and is perpendicular at mid point if the curved reflecting surface is called principal axis.

Question 7

what is center of curvature?

Answer 7

center of the hollow sphere through which the curved surface has been taken out is called center of curvature.

Question 8

what is radius of curvature?

Answer 8

radius of that hollow sphere through which the center of curvature is taken out is called radius of curvature.

Question 9

what is focal length?

Answer 9

the length or distance between the pole and focus of the mirror is called focal length.
