Question

A concave mirror has
mirror has radius
af Curvature
tore doon, write the focal length of
the concave mirror with
proper
Sign​

Answer 1

Explanation:

as the radius of curvature (R)=2m for the concave morrom, its focal length is given by :f=R/2=1m. now,for a distance object (u→∞), image is formed near the focus. so,image distance, V≃f=1m

Answer 2

Answer:

For a concave mirror

Explanation:

• mirror formula :- 1/f = 1/v + 1/u

• f = R/2 and f is always negative in case of a concave mirror/lens

• m (magnification) = h' / h or - v/u(for mirror) and v/u (for lens)

* f is the focal length

u is the object distance

v is the image distance

R is the radius of curvature

h' is the height of the object or size of the image

h is the height of the image or size of the image
