    Sound and light are unrelated forms of energy but in everyday life, they are closely related. The experience of a thunderstorm would be quite different with one element missing. Sight and hearing are two senses that give us the largest volume of information at a time.

    Soundwave refers to the pattern or disturbance caused by the movement of energy traveling through a medium (such as- air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The sources of sound are some objects that cause vibration, such as ringing telephone or a person’s vocal chords. The vibration disturbs the particles in the surrounding medium, those particles disturb those next to them and so on. Hence, the sound is produced. While light waves refer to an electromagnetic wave by which light travels through a medium or vacuum. The white light we see is actually a mixture of light waves of different wavelengths.

    There is two main difference between sound wave and light wave. The first difference is in velocity, the sound waves travel through the air at the speed of approximately 1,100 feet per second while light waves travel through air and the empty space at the speed of 186,000 miles per second. The second difference is that of composition, the sound is composed of longitudinal waves while light energy is composed of transverse waves in an electromagnetic field.
