Answer 1

Answer:

1.Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.

2

f=2r therefore

r=f/2=10 cm

3.A "concave mirror" can provide an "erect and enlarged image" when the "object" is "placed" between "focus and the pole of the mirror"

4.We prefer a convex mirror as a rear-view mirror in vehicles because it gives a wider field of view, which allows the driver to see most of the traffic behind him. Convex mirrors always form a virtual, erect, and diminished image of the objects placed in front of it.
