There are two main differences between sound waves and light waves. The first difference is invelocity. Sound waves travel through air at the speed of approximately 1,100 feet per second; light wavestravel through air and empty space at a speed of approximately 186,000 miles per second. The seconddifference is that sound is composed of longitudinal waves (alternate compressions and expansions ofmatter) and light is composed of transverse waves in an electromagnetic field.
Light waves are electromagnetic waves that do not require a medium to travel through, while sound waves and water waves are mechanical waves that need a medium to propagate. Light waves travel at the speed of light in a vacuum, while sound waves and water waves travel at much slower speeds. Additionally, light waves are transverse waves, while sound waves and water waves can be either transverse or longitudinal.
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
Virtually any wave that is not EMR (electromagnetic radiation) requires a medium through which to move. Sound can move through air, water and many kinds of solid material, but it cannot move through vacuum. Light moves easily through vacuum (no medium) and in fact moves at its highest velocity in vacuum. Waves through a medium involve a rarefaction and compression of the material, and nothing physical actually moves across any great distance. Light is also particle-like so that it propagates through vacuum in the form of massless photons.
The fundamental difference is probably that light waves do not need a "medium" through which to travel.
They are all waves but there are differences between all three.
As waves they have the property that they are repetitive in both time and space. In time the function is repeated once every period, while in space it is repeated every wavelength. The wave moves forward by one wavelength per period, so the speed of propagation is the wavelength times the number of periods per second, otherwise called the frequency.
Light waves are waves in the electric field E and magnetic field H, which are both vector quantities directed at right angles to each other and also to the direction of propagation. The vector product E x H is in the direction of propagation and is named the Poynting vector after John Poynting, Physics prof. at Birmingham University in England. The waves travel at a speed (in free space) equal to a physical constant c, which is defined as 2.99792458 x 108 metres per second.
Sound waves are waves in the air pressure, which is a scalar quantity without any direction, and they travel at about 1100 metres per second.
Water waves are waves in the level of the sea's surface, with the waves moving across the surface and the water particles moving mainly up and down but also forward and back. The waves are produced by wind on the surface and the speed of propagation is linked to the amplitude (how high they are). Large ocean waves can travel at 10-15 metres/second, smaller waves move much more slowly.
Sound waves are longitudinal waves that travel through a medium like air, while water waves are transverse waves that propagate on the surface of water bodies. Sound waves require a medium for propagation, whereas water waves do not. Additionally, sound waves transfer energy by causing particles in the medium to vibrate, while water waves involve the periodic movement of water molecules.
Sound waves and light waves are both types of wave phenomena characterized by their frequency and amplitude, but they differ in their propagation medium and properties. Sound waves are mechanical waves that require a medium (such as air, water, or solids) to travel, while light waves are electromagnetic waves that can travel through a vacuum. Both types of waves exhibit wave-particle duality, allowing them to behave as both waves and particles.
Sound waves are mechanical waves that require a medium (such as air, water, or solids) to travel, while light waves are electromagnetic waves that can travel through a vacuum. Sound waves propagate through compression and rarefaction of the medium particles, while light waves oscillate through electric and magnetic fields. Additionally, sound waves travel at a much slower speed (around 343 m/s in air) compared to light waves (299,792,458 m/s in a vacuum).
Electromagnetic or light waves are transverse waves that do not require a medium (such as air or water) to propagate, whereas water and sound waves are mechanical waves that require a medium for propagation. Electromagnetic waves can travel through a vacuum, whereas water and sound waves cannot. Additionally, electromagnetic waves travel at the speed of light, while the speed of water and sound waves depends on the medium through which they are traveling.
Sound waves, water waves, and light waves are similar in that they all involve the propagation of energy through a medium. They all exhibit wave-like behavior characterized by wavelength, frequency, and amplitude. However, the primary difference is the medium through which they travel - sound waves require a medium (e.g. air, water), water waves occur in bodies of water, and light waves can travel through a vacuum.
they both have waves
light waves do not require a medium to travel through, unlike water and sound waves which both need a medium (water and air, respectively). Light waves are electromagnetic in nature and can travel through a vacuum. They have different wave properties such as wavelength, frequency, and speed compared to water and sound waves.

water waves, light waves, and sound waves
Light, sound, and water are examples of things that travel in waves. Light waves can be seen as colors, sound waves allow us to hear sounds, and water waves are seen in oceans and lakes.

Sound and water waves differ in one main way in terms of source, although they are very alike. Sound waves are generated by a verifiable sound source, such as vibration.
