Question

2. If the diameter of a sphere, of which spherical mirror is a part, is 24 cm, what is the focal
length of the spherical mirror?
​

Answer 1

Explanation:

focal length is half of radius that means r=12cm and focal length is 6 cm

Answer 2

Answer:

Given, Diameter= 24cm

radius of the sphere = 24/2 cm

= 12cm

Now, Given, Radius= 12cm

as we know, f=r/2

= 12/2

= 6cm
