Which statement is correct regarding the propagation of sound and light in different mediums?
I. Sound travels faster in water than in air.
II. Light travels faster in water than in air.
Sound waves travel faster in water than in air due to the closer proximity of water molecules, allowing vibrations to be transmitted more quickly.
