There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
What is not an electromagnetic wave?
Beta rays are not electromagnetic waves because they are charged particles and are capable of getting deflected by the magnetic field. These rays are not pure energy as a photon.
Is sound an electromagnetic wave?
Electromagnetic radiation is the propagation through space of electrical and magnetic waves while sound is the result of small changes in the air pressure that propagate through the air. We can sometimes see electromagnetic radiation (as light) or feel it (as warmth) while we can only hear sound.
Is sound an EM wave if not what kind of wave is it?
If not, what kind of wave is it? No, sound is not an electromagnetic wave. Sound is a longitudinal mechanical (pressure) wave, which requires a medium in which to travel.
Are sound waves electromagnetic in nature?
Since sound shows longitudinal wave nature, they are not electromagnetic waves. They need a medium to propagate. So we can conclude that sound waves are not an electromagnetic wave like light.
What are the 7 types of electromagnetic waves?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
Is light a electromagnetic wave?
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.
What type of wave is sound?
Why is sound 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.
Why electromagnetic wave can travel in vacuum?
An EM wave can travel without a material medium—that is, in a vacuum or space empty of matter—and does not lose energy as it moves. In theory, an EM wave can travel forever. Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum.
What are the three types of waves?
Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves. A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
How do you make an electromagnetic wave?
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
What type of wave is light?
How do we produce sound?
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. … The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
Is sound a longitudinal wave?
A sound wave is a longitudinal wave. Sound waves are essentially a disturbance in air molecules.
What is medium in sound waves?
Sound is a type of energy made by vibrations. These vibrations create sound waves which move through mediums such as air, water and wood. When an object vibrates, it causes movement in the particles of the medium. This movement is called sound waves, and it keeps going until the particles run out of energy.
