Light. Note that light is a special case of electromagnetic waves; but if it isn't visible light, you wouldn't call it a "light wave", just an "electromagnetic wave".
The speed of light in a vacuum has been defined as exactly 299,792,458 meters per second.
The differences between light and sound are as follows:Light can be considered to be made of waves as well as particles. Sound is only a wave. It does not show particle nature.Light waves are electromagnetic waves while sound waves are mechanical waves.Light waves are transverse while sound waves are longitudinal.Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.The speed of light in a medium is constant. The velocity of sound waves can change.In sound waves, the particles of the medium actually oscillate. In a light wave, the electric and magnetic vectors oscillate.Light waves can be polarized, but sound waves cannot.Light waves travel much faster than sound waves. The speed of light is a physical constant. Its value is exactly 299,792,458 metres per second in vacuuum. The speed of sound is 343 metres per second in dry air at 20°C.And finally, a simple one - you can see light while you can hear sound.
Light waves are electromagnetic waves that can travel through a vacuum and do not require a medium to propagate, whereas sound waves are mechanical vibrations that need a medium, such as air or water, to travel. Light waves travel at the speed of light in a straight line, while sound waves travel through a medium by causing particles to vibrate in a wave pattern.
Sound waves and light waves are both forms of energy that travel in waves, but they have different properties and behaviors. Sound waves are mechanical waves that require a medium, such as air or water, to travel through, while light waves are electromagnetic waves that can travel through a vacuum. Sound waves travel slower than light waves and can be reflected, refracted, and diffracted, while light waves can also be polarized and undergo interference. Sound waves are longitudinal waves, meaning they travel by compressing and expanding the medium, while light waves are transverse waves, with oscillations perpendicular to the direction of travel.
Light waves travel at their fastest in a vacuum, where they travel at the speed of light, which is approximately 299,792 kilometers per second.
Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
Similarities: Both light and sound waves are forms of energy that travel in waves. They can both be reflected, refracted, and diffracted. Differences: Light waves can travel through a vacuum, while sound waves require a medium to travel through. Light waves are electromagnetic waves, while sound waves are mechanical waves that require a medium to propagate. Light waves travel much faster than sound waves.
Light waves travel from sun to the earth.
Light waves and sound waves are both forms of energy that travel in waves, but they have key differences. Light waves are electromagnetic waves that can travel through a vacuum, while sound waves are mechanical waves that require a medium, such as air or water, to travel through. Light waves travel much faster than sound waves, at a speed of about 186,282 miles per second in a vacuum, while sound waves travel at a speed of about 767 miles per hour in air. Additionally, light waves are transverse waves, meaning they oscillate perpendicular to the direction of travel, while sound waves are longitudinal waves, meaning they oscillate parallel to the direction of travel.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
yes it travels in waves.
Light waves - electromagnetic waves that can travel through a vacuum at the speed of light. Radio waves - electromagnetic waves used for communication that travel at the speed of light in a vacuum. X-rays - a high-energy form of electromagnetic radiation that can travel at the speed of light. Microwaves - electromagnetic waves commonly used in technology and cooking that can travel at the speed of light.
