What do electromagnetic waves consist of quizlet?

An electromagnetic wave consists of changing electric and magnetic fields. Electromagnetic waves travel as vibrations in electric and magnetic fields. An electric field is region in which charged particles can be pushed or pulled. But light can also as though it is a stream of particles.

What are the three components of electromagnetic waves?

Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E). The spectrum can be ordered according to frequency or wavelength.

What makes electromagnetic waves and water waves different?

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). The speed of a wave is related to both its frequency and wavelength.

Which of the following does not consist of electromagnetic waves?

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.

What are the two parts of an electromagnetic wave?

Electromagnetic waves have an electric (E) field component and a magnetic (H) field component that oscillate in phase and in directions perpendicular to each other.

What are two key features of an electromagnetic wave?

Key Points Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

What are the seven different types of electromagnetic waves?

There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves.

How dangerous are electromagnetic waves?

Electromagnetic wave is dangerous, electromagnetic radiation makes us leukemia, cancer, and cataract. Such rumors about electromagnetic radiation’s risk are in many websites and books. Electromagnetic wave and electromagnetic radiation are invisible, odorless, and of course, vapidly.

What are different uses do electromagnetic waves have?

Uses of Electromagnetic Waves TV and FM radio (short wavelength) Direct line of sight with transmitter (do not diffract) Medium wavelength – travel further because they reflect from layers in the atmosphere

What do waves have both electric and magnetic properties?

Light is a wave of both electric and magnetic fields, but when these waves strike matter, the weaker effect of the magnetic component has been nearly impossible to detect directly.
