Question

An object of height 6 cm is placed at a distance of 24 cm from a concave mirror of focal length 30 cm find position height and nature of image.​

Answer 1

Answer:

Position of image = Behind the mirror

height of image= 30cm

Nature of image= Virtual and erect

Explanation:

h=6cm

u=-24cm

f=-30cm

image height (h¹)=?

image distance (v)=?

1/f= 1/v +1/u

1/-30= 1/v-1/24

by solving this we will get

v=120cm

m=h¹/h= -v/u

by using the above formula we will get

height of the image (h¹)= 30cm
