What are 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 are the 7 properties of electromagnetic radiation?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Who determines the properties of electromagnetic radiation?
In 1862–64 James Clerk Maxwell developed equations for the electromagnetic field which suggested that waves in the field would travel with a speed that was very close to the known speed of light.
What are the properties of electromagnetic radiation Class 11?
Electromagnetic waves are propagated by oscillating electric fields and magnetic field oscillation at right angles to each other.
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 radiation explain?
Radiation that has both electric and magnetic fields and travels in waves. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.
What are 5 properties of electromagnetic waves?
1 Answer
- They are transverse in nature.
- They consist of oscillating electric (E) and magnetic (B) field vectors at right angles to each other and at right angles to the direction of propagation of the wave.
- They can travel through a vacuum.
- They travel at the speed of light in vaccuum, c=3×108m/s.
What are the uses of electromagnetic radiation?
Uses of Electromagnetic Waves
- Radio waves – radio and television.
- Microwaves – satellite communications and cooking food.
- Infrared – Electrical heaters, cooking food and infrared cameras.
- Visible light – Fibre optic communications.
- Ultraviolet – Energy efficient lamps, sun tanning.
- X-rays – Medical imaging and treatments.
Which properties of electromagnetic radiation are inversely related?
Wavelength and frequency are inversely proportional to each other: wavelength × frequency = constant.
Which of the electromagnetic radiation is radioactive?
A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Gamma rays, X-rays and the higher energy range of ultraviolet light constitute the ionizing part of the electromagnetic spectrum.
Which properties of electromagnetic radiation are directly proportionally related?
The energy of electromagnetic radiation is directly proportional to its frequency. The phenomenon of it was given by Planck known as Planck’s law, E = hʋ.
Which property is related inversely en?
Therefore, it can be concluded that electronegativity and metallic properties are inversely related.
