WebDefinitions- (i) Principal focus (F) of a concave mirror – Focus of a concave mirror is the point at which the incident rays, parallel to the principal axis, actually meet after reflecting from the concave mirror. (i) Focal length (f) – Focal length of a concave mirror may be defined as the distance between its focus and pole.

Web4. B. X = centre of curvature, Y = vertex, Z = focal lengthThe PRINCIPAL AXIS is X. A concave mirror's major axis is a hypothetical line that passes through the concave mirror's focus, pole, and center of curvature. Y is the CURVATURE'S RADIUS. The radius of the glass sphere from which the concave mirror was cut is known as the radius of … Web1. Define the principal focus of a concave mirror. 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 called the principal focus of the concave mirror. 2. The radius of curvature of a spherical mirror is 20 cm. WebApr 7, 2024 · The principal focus of a spherical mirror is a point on that spherical mirror's principal axis where parallel light rays intersect (meet) or emerge to deviate after reflection.The Mirror's function is to change the direction in which light travels. The theory says that the convex and concave lenses have opposing directions. fry\u0027s and kroger the same thing
