Answered by ushasri42

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.
