are electromagnetic waves slower than sound waves?

Why do sound waves travel slower than EM waves? Sound waves must have a material medium to propagate. ... It takes time to accelerate the molecules and create a compression wave. EM waves can propagate in vacuum where they use the ultimate speed limit of energy propagation in nature, the speed of light.

What are electromagnetic waves? Electromagnetic waves are non elastic waves in the sense that they don't really need a material medium for their propagation like sound waves do.

Electromagnetic waves vary in wavelength and frequency. Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy. The speed of a wave is a product of its wavelength and frequency.

Electromagnetic Spectrum. ... (This is why sound waves are not typically considered part of the electromagnetic spectrum, since sound requires a medium—such as air or water—through which to propagate, whereas electromagnetic waves have little difficulty in radiating through the vacuum of space.)

The speed of sound through air is about 340 meters per second. ... Light will travel through a vacuum at 300 million meters per second. So they're totally different scales. No information can propagate faster than the speed of light.

~ Electromagnetic waves move the fastest through gases. Since electromagnetic waves do not require a medium to pass through, they are faster in matter that has fewer particles. ... ~ Sound cannot travel in a vacuum because mechanical waves, such as sound waves, require a medium to propagate through.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. ... This proved that radio waves were a form of light!

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. ... Electromagnetic waves are created by the vibration of an electric charge.

1 Answer. Aritra G. 1) Sound waves are longitudinal in nature, i.e. the vibrations happen parallel to the direction of propagation of the wave. ... The EM waves on the other hand are due to oscillating electric and magnetic fields perpendicular mutually and also to the direction of motion.

Propagation of an Electromagnetic Wave Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.

All electromagnetic radiation, of which radio waves and X-rays are examples, travels at the speed c in a vacuum. The only difference between the two is that the frequency of X-rays is very much higher than radio waves.

Electromagnetic waves can travel through water; mechanical waves can only travel through solid matter.

Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.... Electromagnetic waves can be described by means of vibrating electrical and magnetic fields which are mutually perpendicular. The nature of these waves is transverse.

Sound you hear, light you see. Sound is a mechanical wave whereas light is an electromagnetic one. ... Light does not need a medium to travel to, sound does. They are both waves but only light is also a particle.

Radio waves have a lower frequency and longer wavelength as compared to cell phone waves operating at higher microwave frequencies. Microwaves can carry a higher amount of information than radio signals, and are transmitted in narrower beams which can be aimed and focused to a greater degree than radio waves.

A Sound wave is a longitudinal wave whereas, electromagnetic waves are transverse waves. Sound is a mechanical vibration that passes through a medium such as gas, liquid or solid to become a sound. Whereas,Electromagnetic waves, also known as EM wave, is the travel path of electromagnetic radiation or EMR.

Rather, we are talking about the waves that transmit radio signals. The main difference between radio waves and sound waves is that radio waves are a type of electromagnetic wave that can travel when there is no medium, whereas sound waves are a type of mechanical wave that cannot travel if there is no medium.
