Which of them travel faster - light or sound waves?

Light waves travel in vacuum with the speed of light c = 299792458 m/s or 983571056 ft/s.

Sound waves travel at 20°C (68°F) with the speed of sound c = 343 m/s or 1125.33 ft/s.

So light travels 874,030 times faster than sound.

Don't forget that sound needs necessarily air as a medium.

Light does not need a medium; vacuum is O

What tool is used for SONAR?

SONAR (Sound Navigation and Ranging) primarily uses sonar systems that include transducers, which emit sound waves and receive echoes. These systems can be categorized into active and passive sonar. Active sonar sends out sound pulses and listens for their return, while passive sonar detects sounds made by objects in the water without emitting sound waves. Common tools used in sonar applications include echo sounders, hydrophones, and sonar arrays.

no some of the heat is radiated away in forms of light and heat waves

What is the working principle of transmitter?

There are many types of transmitters. Thesimplest is the Amplitude Modulated (AM) transmitter. This is an oscillator that cycles at a predetermined frequency. This oscillator puts out a level of energy that is varied by the sounds that you desire to transmit. This variance is done from 100% of the signal to 0%. The output then is two frequencies combined one at the stations frequency and one at the frequency of the sound transmitted. The receiver throws away the transmission frequency and amplifies the frequency of the sound.Bottom line is you only hear the sound stuck into the transmitter.F.M. is the same as AM but instead of varying power, we vary the frequency with the desire sounds we want to hear. The receiver sees that variance and converts that to sound.Phase shift, DSB, SSB and the others are merely more complex variances to these basics.


What are linear displacement transducers?

"Transducers" are devices that convert one form of energy into another. There are many different transducer types, converting many different forms of energy. One common example would be a microphone, which converts sound waves into an electrical signal for transmission to some type of signal amplifier. (Conversely, another example could be the speaker that receives that amplified signal, and converts it back into sound waves again.) Heat, strain, vibration, and pressure are other examples of energy that can be converted into various output signals. "Displacement" refers to how the transducer receives or measures "input information" through various forms of motion. Stretching, flexing, shaking, and pressures are examples of these motions. "Linear" refers to the design of a transducer, in that it receives information from a source in a linear, or straight, direction. So, a Linear Displacement Transducer is a device that takes some form of input energy fed to it in a straight line, and outputs a converted signal relative to the range of displacement that has taken place. (If you know what a "potentiometer" is, think of a Linear Displacement Transducer as a potentiometer that moves in and out rather than rotates left and right.)

What waves travel faster sound or light?

Light waves travel faster than sound waves.


Do LIGHT WAVES TRAVEL FASTER THAN SOUND WAVES.?

Yes, light waves travel faster than sound waves. Light waves travel at a speed of approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum, while sound waves travel at speeds ranging from around 767 mph (1,225 km/h) in air.


Why do radio waves travel faster than the sound wave?

Radio waves are just low frequency light waves. They travel at the speed of light, much faster than sound waves which are just changes in pressure traveling in waves


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.


What travels faster than light waves and sound waves?

Nothing within the known laws of physics can travel faster than light in a vacuum. However, certain theoretical particles known as tachyons are hypothesized to travel faster than light. Additionally, gravitational waves can also travel at the speed of light.


Why do light waves have a far shorter wavelength than sound waves?

sound waves travel faster slower than light waves In air, sound travels around 300m/s.


What are the differences between light waves and sound waves?

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.


What is the objective of travel faster radio waves or sound waves?

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 do light waves travel faster then sound waves?

Electromagnetic waves travel independently of the medium through which they travel -- while transparent matter can impede its passage, no transfer of energy from molecule to molecule is required as with sound waves and other vibrations. The speed of sound is limited by the motion of molecules, which is faster in denser materials.


Which travels faster-radio waves or sound waves?

Radio wave travel faster than sound wave. Radio wave is the same as light wave except at different wavelength. It travel at speed of light (3 x 108 m/s). Sound wave travel at only 330 m/s and probably can go up to 3,300 m/s in solid medium which is far slower than the speed of light.
