Give a short answer to the question:
 
Explain the path of light rays when they fall on convex and concave mirrors under the following conditions:

1. A ray is parallel to the principal axis.
2. A ray passes through the principal focus.
3. A ray is oblique and strikes the pole.
4. A ray passes through the center of curvature.
 
1. Whenever an and strikes a convex mirror, it becomes and following laws of reflection from the mirror.
 
2. Whenever an incoming ray strikes a concave mirror while travelling through its primary focus, it must be .
 
3. Whenever an incident ray is oblique towards the primary axis and strikes the pole of a concave mirror, it must be .
 
4. Whenever an incoming ray passes through the center of curvature (C) of a concave mirror, it is along the path.
