Question

draw the ray diagram ofimage formed by a mirror in which object distance is negative image distance is positive and magnification is less than 1

Answer 1

Answer:

(a) As magnification is in negative the image will be down the principle axis compared to the object and will form in Concave Mirror.

(b) The distance of image from the object is zero, real and inverted image of the same size is formed at the same place where object is placed.

(c) Spherical mirror has a radius of curvature R and a focal length i.e

F=

2

R

F=

2

50

F=25cm

(d) Figure attached shows the image formation by concave mirror for the given case.
