Solution:-
Given that the radius of curvature(R)=22 cm
From formula,
f=R/2 (Where f=Focal length,R=Radius of curvature)
f=22cm/2
f=11 cm ans...
What is the focal length of a spherical mirror whose radius of curvature is 37 cm?
Solution:-
Given that the radius of curvature(R)=37 cm
From formula,
f=R/2 (Where f=Focal length,R=Radius of curvature)
f=37cm/2
f=18.5 cm
What will be the focal length of a convex mirror whose radius of curvature is 20 cm?
Solution:-
Given that the radius of curvature(R)=20 cm
From formula,
f=R/2 (Where f=Focal length,R=Radius of curvature)
f=20/2
f=10 cm
