Which statement about sound is true?

A. Sound can’t travel through a vacuum
B. Sound can’t travel through glass
C. Sound can’t travel through water
D. None of these

Check Answer

The correct answer is A. Sound can’t travel through a vacuum.
Sound is a type of energy that travels in waves through a medium such as air, water, or solids. However, sound cannot travel through a vacuum, which is an area devoid of matter, because there is no medium for sound waves to travel through. This is why there is no sound in space, where there is a near-vacuum.
Sound can travel through glass and water, as both of these substances are mediums that allow sound waves to pass through. In fact, sound travels faster in water than in air due to water’s higher density.
