What are the properties of electromagnetic radiation?
What are the properties of electromagnetic radiation?
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 is electromagnetic radiation slide share?
It does not require a supporting medium and travels through empty space at the speed of light or • EMR is a form of energy emitted and absorbed by charged particles which exhibits wave-like behavior as it travels through space. It propagates as wave motion at a velocity of c = 3 x 108 m/sec.
Why do different types of electromagnetic radiation have different properties?
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
What is electromagnetic wave and write its two properties?
EM waves travel with a constant velocity of 3.00 x 108 ms-1 in vacuum. They are deflected neither by the electric field, nor by the magnetic field. However, they are capable of showing interference or diffraction. An electromagnetic wave can travel through anything – be it air, a solid material or vacuum.
What are common properties of waves?
However, all waves have common properties—amplitude, wavelength, frequency, and speed. Amplitude describes how far the medium in a wave moves. Wavelength describes a wave’s length, and frequency describes how often it occurs.
What are the applications of electromagnetic radiation?
Electromagnetic waves have a vast range of practical everyday applications that includes such diverse uses as communication by cell phone and radio broadcasting, WiFi, cooking, vision, medical imaging, and treating cancer.
What are the forms of electromagnetic radiation?
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Which properties of electromagnetic radiation are inversely related?
Wavelength and frequency are inversely proportional to each other: wavelength × frequency = constant.
What are the characteristics of electromagnetic radiation?
Some of the characteristics of the electromagnetic radiation is: The electrical and magnetic fields generated by charged particles are mutually perpendicular to each other and are perpendicular to the direction of propagation of wave. There is no medium required for the propagation of an electromagnetic wave.
What represents the different forms of electromagnetic radiation?
Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. All of these, known collectively as the electromagnetic spectrum, are fundamentally similar in that they move at 300,000 km per second, the speed of light.
What are five examples of electromagnetic radiation?
Visible Light Waves. Let’s start with the most visible type of electromagnetic radiation: visible light waves.
What produces electromagnetic radiation?
Electromagnetic radiation is a self-propagating wave of energy that is produced by many contemporary electronic devices. Electromagnetic radiation possesses energy and matter, which is impacted when it encounters another object. This form of energy is thought to possess beneficial, as well as harmful, health effects.
