A 14.5 cm high object is placed 50.0 cm in front of a concave mirror with radius of curvature equal to 30.0 cm. determine the distance, height, and image formed by the mirror.
Answer
The height of the object is ho = 14.5 cm
The object is placed in front of the mirror at a distance of u = 50 cm
The radius of the curvature of the mirror is R = 30 cm
Now,
From the sign convention, the object distance is u = -50 cm
From the sign convention, the radius of curvature is R = -30 cm
The expression for the mirror formula is
Putting all values
v=-21.42cm
Height of image
