Question

define the principal focus of a concave mirror

Answer 1

Explanation:

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.

Answer 2

Answer:

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.

When the object is at focal point: Image is at infinity

When the object is at center of curvature: Image obtained is at center of curvature

When the object is placed at infinity: Image obtained is at the focal point---
