(1) Pole (2) Principle axis (3) Radius of curare (4) Aperture (A) The midpoint of the reflecting surface of spherical mirror (B) The radius of hollow sphere of which the reflecting surface forms a part (C) The imaginary straight line joining the pole and the centre of curvature (D) The width of the mirror from which reflection can take placeMatch the following with correct response.
(1) Pole
(2) Principle axis
(3) Radius of curare
(4) Aperture

(A) The midpoint of the reflecting surface of spherical mirror
(B) The radius of hollow sphere of which the reflecting surface forms a part
(C) The imaginary straight line joining the pole and the centre of curvature
(D) The width of the mirror from which reflection can take place​

Answer 1

Explanation:

1=b

2=a

principal axis - a line that passes through the center of curvature of a lens so that light is neither reflected nor refracted; "in a normal eye the optic axis is the direction in which objects are seen most distinctly" optic axis.

3=c

4=d
