Which statement about the properties of light and sound is incorrect?

A Light travels faster in water than in a vacuum. Correct Incorrect

B Sound travels faster in solids than in gases. Correct Incorrect

C A convex lens focuses light rays at a focal point. Correct Incorrect

D The ampere is the unit of electric current. Correct Incorrect

Detailed Solution

Light travels fastest in a vacuum at approximately 299,792 km/s. In water or any other medium, it slows down due to the medium's refractive properties. This fact highlights the unique behavior of light compared to sound, which indeed travels faster in solids due to better transmission through denser material.
