Question

A concave spherical mirror has a radius of curvature of 100cm. What is it's focal length?​

Answer 1

Answer:

We know,

Focal length (f)=

1

Radius of curvature (R)

⇒Radius of curvature (R)=1×Focal length (f)

Given,

Focal Length, f=100 cm

⇒R=1×f=1×100=100 cm

⇒Radius of curvature (R)=100 cm
