1.	) The focal length of a rear view mirror in a moving car is 1 m. A truck is coming from behind, at a distance of 5 m. Calculate the i) Position and ii) size of the image relative to the size of the truck.
Answer» Radius of curvature, R=2mobject DISTANCE, μ=3.5mfocal length, f= 2R = 22 f=1mfrom MIRROR formula,f1 = μ−v 11 = v1 − 3.51 ⇒ v1 =1+ 3.51 v1 = 79 v= 97 m=0.78mMagification, m=− μv =+ 9×3.57 m= 92 =0.22Image will be formed at 0.78m & will be virtual crect and diminished.Image will be 0.22 times the TRUCK.
