Microwave ovens: The mechanism used is based on the Faraday cage such that the electromagnetic energy within the oven is contained and the exterior is a shield from radiation. They find application in analytical chemistry to reduce noise while making sensitive measurements. Related Physics Articles:

What Are Electromagnetic Waves? Electromagnetic waves are also known as EM waves. Electromagnetic radiations are composed of electromagnetic waves that are produced when an electric field comes in contact with the magnetic field. It can also be said that electromagnetic waves are the composition of oscillating electric and magnetic fields.

In electromagnetic radiation, velocity is expressed as the product of wavelength and frequency, given by Velocity = λν. For electromagnetic waves propagating in a vacuum, the velocity is equal to the speed of light, which is approximately 186,282 miles …

The correct option is D lines of → B cannot end on any material and perfect shielding is not possible ...

Faraday’s law of electromagnetic induction, also known as Faraday’s law, is the basic law of electromagnetism which helps us predict how a magnetic field would interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is …

Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light. It is the basic reason electrons are bound to the nucleus ...

What Is the Electromagnetic Spectrum? The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 10 25 Hz, corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves.

A hypothetical electromagnetic wave is shown in Fig. Find out the wavelength of the radiation. Answer. The distance between two successive peaks or troughs of a wave is defined as its wavelength. So λ = 4 × 2.16 pm = 8.64 pm. Q16. Chlorophyll present in green leaves of plants absorbs light at 4.620 x 10 14 Hz. Calculate the wavelength of ...

An electromagnet can be defined as a magnet which functions on electricity. They are made out of a coil of wire. Learn the various uses and the working principle of electromagnets at BYJU'S.

Electromagnetic Field. The electromagnetic field affects the change in the behaviour of charged objects surrounding a particular place. It extends indefinitely throughout space and is known as electromagnetic interactions. It is a combination of an electric field and a magnetic field and is often considered as the source of the electromagnetic ...
