What Are The Three Main Differences Between Sound Waves And Light Waves?

The three main differences between light and sound waves are as follows :

1) The sound waves have only the characteristics of waves, whereas light has a wave particular duality in nature. They exhibit properties of both waves and particles and are said to be composed of packets of light called photons.

2) The sound waves are perceived by auditory devices such as ears or microphones whereas light waves can be received or seen through visual devices such as the eyes or cameras or other devices that record them on different frequencies like microwave antennae.

3) The speed of sound depends on the medium it is traveling in, whereas the speed of light is a constant and it travels with almost the same speed in different refractive mediums like air or water.
