pls give me radius
then i will edit my answer
The formula for this sum is
r=2f
If radius is 40 cm
then focal length will be 20 cm

BrainpoweredBoy: Then answer will be 20
rehamasad: no i m not may be you are nonsense
rehamasad: how?
rehamasad: give me solution
rehamasad: tell
BrainpoweredBoy: R=2F As we know,r=40 & f=20
rehamasad: hmko focal length find krna h
rehamasad: so radius 40 cm h
rehamasad: aap pura linewise solutions de do please
rehamasad: tell

If the radius of curvature is 150 cm. then the focal length is 75 cm. The light will converge at the focal point, which is a distance of 75 cm from the mirror surface. 2. It's the early stages of the Concave Mirror Lab.
