conditions for ray diagrams
*Those you should draw for convex and concave curved path among two media*​

simplified...

General rules for image formation using ray diagrams:

• Any ray of light that passes through the mirror, is always parallel to the principal axis.
• Any ray of light that passes through the mirror, is always parallel to the principal axis.Any ray of light that passes through the mirror always passes through the principal focus (f) of the mirror after reflection.

1st pic is of concave mirror,2nd is convex mirror and the 3rd one is an example

Answer 2

Explanation:

two ray diagrams

Convex mirror has two ray diagrams because its principal focus and the centre of curvature lies behind its reflecting surface.
