2. WAVES
A wave is an oscillation accompanied by a transfer of
energy that travels through space or mass.
Wave motion transfers energy from one point to another.

3. WAVE MOTION
A wave motion is the propagation of disturbance
from the point of a medium to other parts of it.

4. Types of waves
A mechanical wave is just a disturbance that propagate through a medium.
The medium could be air, water, a spring, the Earth, or even people.
Example of mechanical wave: sound, water waves, earthquakes, etc.
An electro magnetic wave is simply light of a visible or invisible
wavelength. Oscillating intertwined electric and magnetic fields comprise
light. Light can travel without medium.

5. A matter wave is a term used to describe particles like electrons that
display wavelike properties.
A gravity wave is a ripple in the “fabric of space time” itself. They
are predicted by Einstein’s theory of relativity, but they’re very
difficult to detect.

6. Types of Mechanical waves
Mechanical waves need a physical medium. The particles in the medium can move in two
different ways: either perpendicular or parallel to direction of the wave itself.
In a longitudinal wave, the particles in the medium move parallel to the direction of the
wave.
In a transverse wave, the particles in the medium move perpendicular to the direction of
the wave.
A surface wave is often a combination of the two. Particles typically move in circular or
elliptical paths at the surface of the medium.

7. Longitudinal Parallel
Transverse Perpendicular
Surface Combo

8. A transverse wave is a wave in which the
particles of the medium vibrate perpendicular
to the direction of propagation of the wave.

9. Examples of transverse waves
 Light waves
 Radio waves
 Water wave
 UV rays
 X rays

10. Longitudinal waves
A longitudinal wave is a wave in which the
particles of the medium vibrate in a direction
parallel to the direction of propagation of the
wave.

11. Examples of longitudinal waves
 Sound waves
 Waves in slink
 Vibration in gases
 Oscillation in spring
 Tsunami waves

12. Characteristics of transverse waves
a) Wave length: It is the distance between any two
consecutive points which are in the same state of
vibration.
b) Crust: It is the elevated portion of the wave.
c) Trough: It is the depressed portion of the wave.
d) Frequency: It is the number of cycles per second

13. 
Velocity of a wave
= frequency of the wave * wavelength of the wave
