Question

an object is placed at a distance of 15cm form a convex mirror and an image is formed at a distance of 5cm form the mirror calculated the radius of curvatur of the mirror

Answer 1

u= -15cm
v= 5cm
f= ?
and to find a radius of curvature formula is
R=2f
so, using mirror formula
1/f=1/u+1/v
putting values
1/f=1/-15+1/5
1/f=5+(-15)/75
1/f= -10/75
cross multiple
-10f=75
f=75/-10
f= -7.5
So, R=2f
2×-7.5
R= -15

Answer 2

Answer:

u= -15cm

v= 5cm

f= ?

and to find a radius of curvature formula is

R=2f

so, using mirror formula

1/f=1/u+1/v

putting values

1/f=1/-15+1/5

1/f=5+(-15)/75

1/f= -10/75

cross multiple

-10f=75

f=75/-10

f= -7.5

So, R=2f

2×-7.5

R= -15
