A tub is filled with a transparent liquid to a height of 30.0 cm. The apparent depth of a coin lying at the bottom of the tub is found to be 16.0 cm. The speed of light in the liquid will be:
(A) \(1.6\times 10^8\ m/s\)
(B) \(2.0\times 10^8\ m/s\)
(C) \(3.0\times 10^8\ m/s\)
(D) \(2.5\times 10^5\ m/s\)
