Electromagnetic Waves Class 12th: MCQ & Extra Questions (2024)

FAQs

What is electromagnetic waves Mcq? ›

Electromagnetic waves or EM waves: The waves that are formed as a result of vibrations between an electric field and a magnetic field and they are perpendicular to each other and to the direction of the wave is called an electromagnetic wave. The accelerating charged particle produces an electromagnetic (EM) wave.

What are electromagnetic waves answers? ›

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

What is the velocity of the electromagnetic wave Mcq? ›

Characteristics of Electromagnetic Wave

These waves travel at a constant velocity of 3 x 108 m/s in a vacuum. Electromagnetic waves do not require a medium to travel. The frequency of the wave remains unchanged but wavelength changes when it travels from one medium to another.

What is electromagnetic wave class 12th physics chapter? ›

Electromagnetic waves are generated when electrically charged particles oscillate (accelerating charges). The vibration of electric field associated with the accelerating charge generates a vibrating magnetic field. Both these vibrating electric and magnetic fields give rise to EM waves.

What is the common characteristic of all the EM waves MCQ? ›

The three characteristics of electromagnetic waves are: Electromagnetic waves are transverse in nature. Electromagnetic waves consist of oscillating magnetic and electric fields that, are perpendicular to each other. Electromagnetic waves travel through vacuum with same speed, 3 × 10 8 m / s .

When there is a charge ____ an electromagnetic wave could be created? ›

A charge falling in an electric field is accelerated by the electric force and thus produces EMWs.

What are the 7 types of radiation? ›

From long to short wavelength, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. Energy is propagated through space in the form of electromagnetic (EM) waves, which are composed of oscillating electric and magnetic fields.

What is the highest frequency wave? ›

Gamma-rays have the highest frequency. They also have the highest energies and shortest wavelengths. Radio waves have the lowest frequencies and Highest wavelengths. The order of these waves from highest to lowest energies is- Gamma rays > X rays > UV rays > visible light > infrared radiation > radio waves.

What is the formula for EM waves Class 12? ›

16.6: The Electromagnetic Spectrum

The relationship among the speed of propagation, wavelength, and frequency for any wave is given by v=fλ, so that for electromagnetic waves, c=fλ, where f is the frequency, λ is the wavelength, and c is the speed of light.

What is the speed of an electromagnetic wave called? ›

All of these electromagnetic waves (whether radio, visible or gamma) travel at the same speed. They all travel at the 'speed of light' through a vacuum, that is at 3 × 10 8 m s-1.

Which electromagnetic wave has the highest velocity? ›

Gamma ray is a photon moving with the highest speed 3×108 m/s.

What is the phase difference between electric and magnetic field in electromagnetic waves? ›

Most of the researchers think that the phase difference between electric and magnetic fields of the EM waves is .

What is the formula for the speed of EM waves? ›

The speed of an electromagnetic wave in a material medium is given by v=1√με, μ being the permeability of the medium and ε is its permittivity.

How is power transmitted in EM waves? ›

Power is transmitted in an electromagnetic wave in the direction of propagation of the wave which is given the cross product of both magnetic field and electric field. Hence the power transmitted is in a direction perpendicular to both fields.

What is the formula for intensity of EM waves? ›

Section Summary. The energy carried by any wave is proportional to its amplitude squared. For electromagnetic waves, this means intensity can be expressed as Iave=cϵ0E202 I ave = c ϵ 0 E 0 2 2 , where Iave is the average intensity in W/m2, and E0 is the maximum electric field strength of a continuous sinusoidal wave.

What are electromagnetic waves? ›

Electromagnetic waves are a form of radiation that travel though the universe. They are formed when an electric field (Fig. 1 red arrows) couples with a magnetic field (Fig. 1 blue arrows).

What is an electromagnetic short answer? ›

What is an electromagnet? An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.

What is an electromagnetic wave quizlet? ›

A electromagnetic wave is a transverse wave that involves the transfer of electric and magnetic energy. An electromagnetic waves is made up of vibrating electric and magnetic fields that move through space or some medium at the speed of light.

What is electromagnetic spectrum mcq? ›

The whole distribution of electromagnetic radiation as per frequency or wavelength is referred to as the electromagnetic spectrum. In a vacuum, all electromagnetic waves travel at the speed of light, but at a variety of frequencies, wavelengths and photon energies.
