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