What are electromagnetic waves and their properties?
Electromagnetic waves consist of two waves oscillating perpendicular to each other. One is the oscillating electric field and the other one is an oscillating magnetic field. The direction of propagation of the wave is perpendicular to the electric field and the magnetic field.
How are electromagnetic waves represented mathematically?
A mathematical representation of electromagnetic wave is given by the two equations E = E cos (kx – wt) and B=B cos(kx-ot), where is the amplitude of the electric field and B is the amplitude of Othe magnetic field.
What are the 7 electromagnetic waves describe each?
The electromagnetic 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) light, X-rays and gamma-rays.
What are electromagnetic waves write any four properties?
Expert Answer:
- Characteristic of electromagnetic waves are as follows: –
- (i) They do not require any material medium for their propagation.
- (ii) The oscillations of and are perpendicular to each other and are in same phase.
- (iii) They are transverse in nature.
- (iv) They travel through vacuum with same speed,
What are properties of a wave?
What are the main properties of waves? The basic properties of a wave are wavelength, frequency, time period, speed and amplitude.
What are the 4 Maxwell equations?
The four Maxwell equations, corresponding to the four statements above, are: (1) div D = ρ, (2) div B = 0, (3) curl E = -dB/dt, and (4) curl H = dD/dt + J. What force slows motion?
Which property is unique to electromagnetic waves?
Property 1: Electromagnetic waves are transverse in nature. Property 2: They propagate by varying electric fields and magnetic fields, such that these two fields are at right angles to each other and at a right angle with the direction of propagation of the wave. Property 3: Electromagnetic waves travel with a constant velocity in vacuum.
What do waves have both electric and magnetic properties?
Graphical Representation of Electromagnetic Waves. Electromagnetic waves are shown by a sinusoidal graph.
What are the seven different types of electromagnetic waves?
Radio Waves: Instant Communication.
What are five properties of waves?
– E → 0 is the vector polarization and | E → 0 | is the magnitude. – ω is the radial frequency. It is related to the ordinary frequency f through ω = 2 π f. – k → is the wave vector. It quantifies wavelength and the directio
