Question

the focal length of a convex mirror whose radius of curvature is 32cm​

Answer 1

Answer:

Focal length = 16cm

Explanation:

We know that,

Radius of curvature = 2 × Focal length

or

$\boxed{R = 2f}$

From this equation we get,

f = R/2

Given that,

Radius of curvature = R = 32cm

Focal length = f = ?

Putting the values we get,

f = 32/2

f = 16 cm

Answer 2

Answer:

f=16cm

Explanation:

We know that the focal length of a convex mirror is twice its radius of curvature.

therefore, r=2f,

or, f =  r/2,

f = 32/2 = 16 cm
