Question

Sound wave cannot travel through
A. Solid
B. Liquid
C. Gases
D. vacuum

Answer 1

Hint: the order of traveling speed of light and sound is opposite and the order of traveling speed of light is vacuum > gases > liquid > solid.
The light can not travel through solid. The speed of light in solids is zero.

Complete step by step answer:
 In our daily life, we hear sound or noise but we don't know the sound propagates from one place to another place. So the answer is sound travels in the form of a wave that's why we use the term sound wave instead of only sound in physics.
When a wave travels the particles of the medium vibrates and due to the vibration of the particles, the sound is produced. That is why sound waves have to need a medium to travel. So it can not travel through a vacuum.
The speed order of sound wave is
       Solid > liquid > gases > vacuum.
The speed of sound is maximum in the solid and all the solid material the sound wave travels fast in steel. The speed of sound in the vacuum is zero.
The answer is (D)
Additional Information:
There are two types of waves: longitudinal waves and transverse waves
A longitudinal wave is a wave in which the particle is vibrated or moved forth and back in the same direction of the medium. A sound wave is the type of longitudinal wave.
A transverse wave is a wave in which particles move up and down. Electromagnetic waves are an example of a transverse wave.
Note:
The student has to remember the main concept of a sound wave traveling is to vibrate the particle of the medium and we know that in a vacuum no medium means no particle available for vibration so without vibration sound waves can not be traveled through a vacuum.
