(b) Where is the image located? (c) Is the image real or virtual? (d) What is the magnification of the mirror? (e) Is the image enlarged or reduced? (f) What is the height of the image? (g) Is the image erect or inverted? 8. A spherical concave shaving mirror has a radius of curvature of 30 cm. A person is located 10 cm in front

Explanation / Answer

a]

Radius of curvature of the mirror will be infinity since the given mirror is a plane mirror which has zero curvature.

b] Image is located at a distance of 30 cm from the mirror which also happens to be the object distance.

c] Image produced is virtual since the image is on the same side as the object.

d] Magnification of the image is 1 since the image size will be the same as the object size due to zero curvature of the mirror.

Therefore the height of the image will also be 1 cm.

The image produced will be erect.
