All electormagnetic waves travel at the same speed-about 300,000,000 meters per second in a vacuum. This rate can also be expressed as 300,000 kilometers per second. At this speed, light from the sun travels the 150,000,000 kilometers to Earth in about 8 minutes. When electromagnetic waves travel through a medium such as the atmosphere or glass, they travel more slowly. But even at slower speeds, electomagnetic waves travel roughly about one million times faster than sound can travel through air.
Electromagnetic waves in vacuum move about 881 thousand times
as fast as sound moves in sea-level air.
What else can I help you with?
How much faster are electromagnetic wave than sound waves?
Electromagnetic waves in vacuum move about 881 thousand timesas fast as sound in sea-level air.
Electromagnetic radiation and sound waves travel at the same speed?
No, electromagnetic radiation (such as light) travels faster than sound waves. In a vacuum, light travels at a speed of approximately 186,282 miles per second, while the speed of sound waves is much slower, around 767 miles per hour in air.
What travel faster a radio signal or sound in air explain?
Radio signals travel at (essentially) the speed of light, as they are electromagnetic waves like light. Sound waves travel at roughly 1200 km/h. Now you have enough information to answer your own question.
Which phenomenon do em waves exhibit that sound waves do not?
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.
What are some similarities and differences between the light and sound waves?
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.
How much faster are electromagnetic wave than sound waves?
Electromagnetic waves in vacuum move about 881 thousand timesas fast as sound in sea-level air.
How much pollution does a electromagnetic wave cause?
Electromagnetic waves only cause sound pollution because they are sound waves.
Electromagnetic radiation and sound waves travel at the same speed?
No, electromagnetic radiation (such as light) travels faster than sound waves. In a vacuum, light travels at a speed of approximately 186,282 miles per second, while the speed of sound waves is much slower, around 767 miles per hour in air.
How much faster are light waves than sound waves?
About a million times faster
Do light and sound both move in waves?
Yes, both light and sound can be described as waves. Light waves are electromagnetic waves, while sound waves are mechanical waves. They both propagate through a medium, although light can also travel through a vacuum.
Why sound waves faster than light waves?
they aren't, they are much much slower.

How are sound waves and eletromagnetic waves different?
Sound waves are mechanical waves that require a medium to propagate, such as air or water, while electromagnetic waves can travel through a vacuum, like in space. Sound waves are longitudinal waves that transmit energy through the vibration of particles, while electromagnetic waves are transverse waves that consist of oscillating electric and magnetic fields. Additionally, sound waves move at a much slower speed than electromagnetic waves.
Why sound waves change into electromagnetic waves in telephone?
Because an electric signal is much easier to transfer over long distances than a sound is.
If a sound wave and an electromagnetic wave have the same frequency which has the longer wavelength?
Wavelength is inversely proportional to frequency, but it is directly proportional to the velocity of propagation. Since sound propagates through air much more slowly than EM waves propagate through the atmosphere or the vacuum of space, the wavelengths of sound waves are much smaller for identical frequencies.
