They never do.
In air, light waves travel about 871 thousand times faster than sound waves.
speed of light
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
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 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.
Light waves travel at a greater speed than sound waves in a vacuum, moving at approximately 186,000 miles per second. In comparison, sound waves travel much slower through air, at around 767 miles per hour.
Electromagnetic waves can travel through a vacuum, while sound waves require a medium (such as air, water, or solids) to propagate. Additionally, electromagnetic waves can travel at the speed of light, while sound waves travel at a much slower speed.
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.
Light energy consists of electromagnetic waves that travel at the speed of light, while sound energy consists of mechanical waves that travel at a much slower speed. Light energy does not require a medium to travel through, whereas sound energy does. Light energy can travel through a vacuum, whereas sound energy cannot.
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.
Light is electromagnetic radiation, while sound is the vibration of air. While sound travels at around 1,100 feet per second, light travels at a speed of 186,000 miles per hour. Also, sound requires a solid, liquid or gas to travel while light can travel through empty space.
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.
