The driving mirror of a car has a radius of curvature of 1m. A vehicle behind the car is 4m from the mirror. Find the image distance behind the mirror.
Answer Details
A driving mirror is always a convex mirror which is always of negative focal length and always forms a virtual image
Thus if r = 1m = 100cm f = 1/2 = -50 ∴ if U = 4cm = 400cm f = -50cm
