does sound travel faster than light in air?
434630
The speed of sound through air is about 340 meters per second. It's faster through water, and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. ... No information can propagate faster than the speed of light.

Below the surface, sound waves pass directly through the water and into your head. You're witnessing evidence that water is a good conductor of sound. For starters, sound travels through water five times faster than it travels through air.

At supersonic speeds (those greater than the local sound speed), there is no sound heard as an object approaches an observer because the object is traveling faster than the sound it produces. Only after the object has passed will the observer be able to hear the sound waves emitted from the object.

Light and sound are not on the same spectrum. Light belongs to the electromagnetic spectrum but sound does not. ... Sound however, is a longitudinal wave - a wave that vibrates in the direction that it is travelling. Sound requires a medium to travel through whereas electromagnetic waves like visible light do not.

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.

Radio waves travel like light waves. ... They transmit radio waves through space to antennas here on the ground.) Sound travels at approximately 1,100 feet per second (766 miles per hour). Radio waves travel at the speed of light, which is approximately 186,000 miles per second.

While they are both forms of energy that travel in the form of waves, there are vital differences between sound waves and light waves. Sound and light travel at significantly different speeds. Light waves move at speeds that are nearly one million times faster than sound waves are capable of traveling.

['Faster-than-light (also superluminal or FTL) communications and travel are the conjectural propagation of information or matter faster than the speed of light.', 'The special theory of relativity implies that only particles with zero rest mass may travel at the speed of light.']

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. ... This enables sound to travel much faster through a solid than a gas.

Faster-than-light (also superluminal or FTL) communications and travel are the conjectural propagation of information or matter faster than the speed of light. The special theory of relativity implies that only particles with zero rest mass may travel at the speed of light.

Sound waves are affected by gravity because gravity affects the density of matter. We know that sound travels faster in water because the density of water is higher than air. The atmosphere is more dense near the surface of the Earth. ... Sound waves travel faster near the surface of the Earth.

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

Sound travels in waves and exists only within a medium. Light also travels in a wavelike manner but light has electric and magnetic properties and accordingly it is an electromagnetic (EM) wave. Sound travels at 343 m/s in air and light travels through all mediums at almost 300,000,000 m/s.

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space.

For the first time, scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertson's team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative.

Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second.

For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. ... Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.
