Space Communication:- It refers to sending, receiving and processing of information through space. There are four odes of space communication.
Young’s double slit experiment:- (For interference light)
To give sense to the probability approach, Schrodinger in1926 derived an equation known after his name as Schrodinger's wave equation. This equation is the ba
(1) These waves propagate in the forward direction of medium with a finite velocity.
(2) Energy and momentum are transmitted in the direction of propagation of wave
Electromagnetic Wave theory – given by Clark Maxwell. Main points are
energy is emitted from any source continuously in the form
Dual nature of matter – radiation-
The wave associated with a particle is called matter wave or de Broglie wave.

(1) Wavelength : (i) It is the length of one wave.
(ii) Wavelength is equal to the distance travelled by the wave during the time in which any one
Interference of light:- “It is the phenomena of redistribution of light energy due to superposition of light waves from two coherent sources.”
MODULATION:-
It is defined the superstition of low frequency base band signal (modulating signal) on a high frequency carrier wave. The resul
Super position principle:-
“According to this principle, when two or more waves travelling through a medium superimpose each other, a new wav
Diffraction of light:- “the phenomenon of bending of light around the sharp corners of an obstacle and spreading into the geometrical should is called d
Type of diffraction:-
Fresnel diffraction : in this type of diffraction, the source and screen are at finite distance from
When two sets of progressive wave trains of same type (both longitudinal or both transverse) having the same amplitude and same time period/frequency/wavelength travelling wit

Stability of an atom – According to Bohr electron revolving around the nucleu
Coherent sources of light:- “Two sources of light are said to be coherent if they emit light waves of same wavelength and I same phase or having a const
ECG (electro cardio graph):
A permanent record of the electric events occurring during a cardiac cycle, made on a graph paper in the form of a wave
A changing electric field produces a changing magnetic field and vice versa which gives rise to a transverse wave known as electromagnetic wave. The time varying electric and
When a sound wave travels through a medium such as air, water or steel, it will set particles of medium into vibration as it passes through it. For this to happen the medium m
Organ pipes are the musical instrument which are used for producing musical sound by blowing air into the pipe. Longitudinal stationary waves are formed on account of superimp
Electromagnetic waves
It is a disturbance which carries energy in space due to the simultaneously time varying mutually perpendicular electric and

When sound waves are incident on a boundary between two media, a part of incident waves returns back into the initial medium (reflection) while the remaining is partly absorbe
Whenever there is a relative motion between a source of sound and the listener, the apparent frequency of sound heard by the listener is different from the actual frequency of
