What does light wave mean?

What does light wave mean?

noun. Physics. An electromagnetic wave by which light travels through a medium or vacuum. ‘the white we see is actually a mixture of light waves of different wavelengths’

What are light waves an example of?

Light, X-rays, and microwaves are all examples of electromagnetic waves; even if you cannot recall if they are longitudinal or transverse, they are all members of the same phenomenon and will have the same type of wave transmission.

What are light waves used for?

Visible light is the light we can see, so is used in photography and illumination. It is also used in fibre optic communications, where coded pulses of light travel through glass fibres from a source to a receiver.

What is a light wave in physics?

A light wave is an electromagnetic wave which travels through the vacuum of outer space. Light waves are produced by vibrating electric charges., An electromagnetic wave is a transverse wave which has both an electric and a magnetic component.

Why is light considered a wave?

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM – you have light. So, Maxwell’s equations do say that light is a wave.

What is the definition of light waves?

light wave An electromagnetic wave that stimulates the retina or other optical sensors.

What does light waves mean?

light wave. noun. Physics. An electromagnetic wave by which light travels through a medium or vacuum. ‘the white we see is actually a mixture of light waves of different wavelengths’. ‘During the course of the laser pulse, the electric field of the light wave oscillates about a dozen times.’.

What is light wave?

Light as a wave: Light can be described (modeled) as an electromagnetic wave . In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM – you have light.
