Difference Between Sound Waves and Light Waves

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.

Sound Waves vs Light Waves

The main difference between sound waves and light waves is that the light waves are categorised as electromagnetic waves, and due to this reason, these are visible to the mortal eyes, but sound waves are mechanical waves and can not be seen. Sound waves are incapable to travel through a vacuum, but light waves can as they do not require any kind of means in order to travel.

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 it travels through a vacuum which is without any matter.

What are Sound Waves?

Sound waves exist as longitudinal waves. These waves travel through with the help of different mediums such as air and water.

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 travelling 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.

Main Differences Between Sound Waves and Light Waves

  1. Sound waves are known as longitudinal waves, whereas light waves are transverse.
  2. Sound waves are generated by oscillating particles of the medium, while light waves are produced by charged particles of the oscillating of the medium.

Conclusion

Sound waves and light waves are two basic phenomenons and part of our daily lives. They keep a balance on the earth, and we perceive these two waves with the help of our five senses.

Both sound waves and light waves function as energy. Light waves also play a part to warm the earth. These two waves are very distinct from each other and have different functions and goals.

The technical terms related to these two waves might be confusing, but their fundamental states are completely different and remarkable.
