Sound Waves vs Light Waves: Difference and Comparison

We all have been tortured by the lessons of physics. But as physics is a culmination of natural things, we can not run far from it.

Key Takeaways

  1. Sound waves are mechanical waves that require a medium to travel.
  2. Light waves are electromagnetic waves that do not require a medium to travel.
  3. Sound waves travel slower than light waves.

Sound Waves vs Light Waves

Sound waves are mechanical waves that require a medium, like air or water, to travel and are perceived by the sense of hearing. Light waves are electromagnetic waves that can travel through the vacuum of space at the speed of light and are perceived by the sense of sight.

Sound Waves vs Light Waves

Longitudinal is the category of sound waves. These are mechanical waves and can travel through all three states that are solid, liquid, and gas.

Electromagnetic light waves are competent to travel without the help of any medium and, thus travel through a vacuum which is without any matter.

According to physics, sound is a vibration that propagates a wave, and this wave transmits through mediums like gas, liquid or solid.

Sound waves can be divided into two categories – compression and rarefaction. In compression, molecules of sound waves are compressed together.

Sound waves are called mechanical waves. Sound waves travel through air and water effortlessly, but they are incapable of traveling through a vacuum.

What are Light Waves?

Light is a part of the electromagnetic spectrum. This radiation is given to us by stars like the sun in the case of the earth.

Light waves do not depend on any sort of medium to travel, and this is why they can travel easily through a vacuum. In a vacuum, the speed of light waves is approximately 186,282 miles per second.

Light waves have three measurable properties, these are amplitude, frequency, and wavelength. Each wave of light possesses a wavelength.
