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.
What are the similarities and differences between sound waves and electromagnetic waves?
Sound waves are longitudinal waves that is, are transmitted in the same direction of oscillation of the particles in the medium. Electromagnetic waves are transverse ie, the electric and magnetic fields, which are perpendicular to each other, oscillate perpendicularly to the direction of wave propagation.13 мая 2014 г.
What do sound waves and water waves have in common?
Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling.
What’s the difference between sound waves and electromagnetic?
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.
What is the similarities between mechanical and electromagnetic waves?
Unlike mechanical waves, which require matter, electromagnetic waves can travel through empty space, as well as through liquids, solids, and gases. There are many similarities between light waves and mechanical waves. They can both be measured by their amplitude, wavelength, and frequency.
What do electromagnetic waves have in common?
They all have things in common. In a vacuum, they all travel at the same speed – the speed of light – which is 3 × 108 m/s. They are all transverse waves, with the oscillations being electric and magnetic fields. Like all waves, they can be reflected, refracted and diffracted.
What are sound waves created by?
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. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
What are the two types of waves?
Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
What is the difference between water waves and sound waves?
Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They’re also called longitudinal waves because the air vibrates along the same direction as the wave travels.21 мая 2020 г.
Is sound 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.
Do sound waves travel faster than electromagnetic waves?
Unlike water waves, electromagnetic waves always travel at the same speed (3 hundred million metres per second) and sound waves all travel at the same speed in a given medium (for example, approximately 340 metres per second in air).2 мая 2011 г.
Does sound travel in electromagnetic waves?
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.
Are sound waves electromagnetic or mechanical?
Sound is a mechanical wave and cannot travel through a vacuum. Light is an electromagnetic wave and can travel through the vacuum of outer space.
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.
