You asked: Which of the following produces electromagnetic waves?

Electromagnetic waves are produced when an electric charge vibrates or accelerates. 2) How fast does light travel in a vacuum? The speed of light in a vacuum, c, is 3.00*10^8 meters per second.

What produces electromagnetic wave?

Electromagnetic waves are produced whenever electric charges are accelerated. This makes it possible to produce electromagnetic waves by letting an alternating current flow through a wire, an antenna. The frequency of the waves created in this way equals the frequency of the alternating current.

Which one can be used to produce an electromagnetic wave?

To generate electromagnetic waves we need accelerating charge particle.

How electromagnetic wave is produced and propagated?

The spark current oscillates at a frequency (ν), which is a characteristic of the circuit. … The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produce a formation that propagates as an electromagnetic wave.

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. To tour the electromagnetic spectrum, follow the links below!

What kind of waves are electromagnetic wave?

EM waves are ‘transverse’ waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves). The highest point of a wave is known as ‘crest’, whereas the lowest point is known as ‘trough’.

Which of the following Cannot produce electromagnetic waves?

Beta rays are not electromagnetic waves

Beta rays also known as beta radiation is obtained through the emission of an electron. 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 is transferred by electromagnetic waves?

In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.

What is a wave How is it produced?

Waves are created by energy passing through water, causing it to move in a circular motion. … Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

How are electromagnetic waves produced Class 12?

Electromagnetic waves are produced by accelerating charged particle. When the charge moves with acceleration, both the magnetic and electric fields change continuously. This change produces electromagnetic waves. Accelerated charge is the source of energy of these waves.

What are the 4 types of waves?

Types of Waves – Mechanical, Electromagnetic, Matter Waves & Their Types.

What are the components of an electromagnetic wave?

Electromagnetic waves have two components: an oscillating electric field and a perpendicular, comoving magnetic field which oscillates at the same frequency, but with a phase shifted by 90°. They describe the movement of a packet of energy between two points.

What are the types of radiation?

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.
