Question

*Write all the rules for drawing Ray diagram By using concave mirror all

six position ray diagram obtained by the concave mirror.​

Answer 1

Answer:

In an arithmetic progression, the first term is

a natural number and the common difference is

a whole number. If the first term is decreased by 2

and the third term is increased by 10, the first three

terms would be in geometric progression. The

common difference can be

(A) 4 (B) 8 (C) 16 (D) 14

Answer 2

Answer:

Rules for drawing geometric images infront of a concave mirror are:

1.if the ray incidents on the concave mirror parallel to the principal axis then the ray will reflect through the focus.

2. if the ray incidents on the concave mirror through focus it will reflect parallel to the principal axis.

3.if the ray incidents on the concave mirror through centre of curvature then the light will be reflected through the way of incidence.

4.if it incidents at the pole of the mirror then it will be reflected according to the law of reflection.
