Question

the convex mirror has focal length 0.5 m,it's radius of curvature is ​

Answer 1

Explanation:

f=0.5 = 5/10= 1/2

f= r/2, = 1/2=r/2 = r = 1/2×2= 1.....(ans)

Answer 2

1m

Explanation:

For spherical mirrors 2×focal lenght(f) = radius of curvature (r) i.e 2f= r

so putting the values

2×(0.5)= r

r= 1m
