Light travels faster than sound ,because sound can only travel waves.
Explanation:
Given that,
Size of object, h = 0.066 m
Object distance from the lens, u = 0.210 m (negative)
Focal length of the converging lens, f = 0.14 m
If v is the image distance from the lens, we can find it using lens formula as follows :
(a) Magnification,

(b) Magnification, 
h' is image height

Hence, this is the required solution.
