Question

An object is placed at a distance of 12 cm in front of a concave mirror of radius of curvature 30 cm. List 4 characteristics of the image formed by the mirror.

Answer 1

Hi
Hope this helps :)

Answer 2

Mirror formula : 1/f=1/v+1/u

R=2f

R/2=f

therefore,

f= 12/2

f=6

u=12

v=?

1/15=1/v+1/12

1/15-1/12=1/v

12-15/180 =1/u [ here we took the lcm for 12 nd 15]

3/180=1/u

1/60=1/u

v=60

therefore the image formed is virtual,magnified, erect,laterally inverted.
