1. what is the main difference between mechanical and electromagnetic waves (1 point)?

EM waves do not propagate in a medium, whereas mechanical waves need one to exist. For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium.

Mechanical waves are the waves that requires a medium to travel. Electromagnetic waves are the waves are the waves that do not require medium but it travels with the help of energy packets called quanta. ... The similarities are, they are all waves.

An electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. ... A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.

All light waves are examples of electromagnetic waves. ... A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave.

Properties of electromagnetic waves An electromagnetic wave is perfectly happy to do that. An electromagnetic wave, although it carries no mass, does carry energy. It also has momentum, and can exert pressure (known as radiation pressure).

Both are electromagnetic waves, quantized as photons. The only difference is the frequency of oscillation. Only wavelengths between 390 and 700 nm (approximately) are visible to humans. Radio waves are much longer (have much lower frequency).

Electromagnetic (EM) waves are transverse waves. Their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel. All electromagnetic waves: transfer energy as radiation from the source of the waves to an absorber.
152721
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. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).

electromagnetic waves are a type of mechanical waves, specifically a transverse wave. they transfer energy. electromagnetic waves dont need a medium to travel through but mechanical waves do.
663320
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.
987365
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.

As a mechanical wave travels through a medium, it loses energy to the medium. ... Non-mechanical waves are waves that do not require a medium for the transfer of their energy to occur. Electromagnetic waves are the only type of non-mechanical waves. They can travel through the vacuum of space.

Electromagnetic waves. Electromagnetic waves are transverse waves. Their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel.
54212
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.
1246069
Mechanical waves need matter to transfer energy, while electromagnetic waves do not, they can travel through space or a vacuum. Electromagnetic waves include the electromagnetic spectrum (This includes visible light, radio waves, gamma rays, x-rays, ultraviolet rays, infra-red waves, and microwaves.)

Electromagnetic waves are transverse waves with a wide range of properties and uses. Sound waves are longitudinal waves.
