This document discusses different types of waves, including transverse and longitudinal waves. It defines transverse waves as waves where particles of the medium vibrate perpendicular to the direction of propagation. Longitudinal waves are defined as waves where particles vibrate parallel to the direction of propagation. Key wave properties like wavelength, amplitude, and frequency are also defined. Wavelength is the distance between two consecutive points in the same state of vibration, amplitude is the maximum displacement from the mean position, and frequency is the number of cycles per second.

3. WAVE MOTION
Wave motion is the propagation of
disturbance from the point of a
medium to other parts of its.

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

10. Wave length
Wave length of a wave is the distance between
any two consecutive points which are in the
same state of vibration.

11. AMPLITUDE
It is the maximum displacement of a particle
from the mean position
LB is the amplitude

12. FREQUENCY
Frequency is the number of cycles per second.

13. 2. longitudinal wave
A long 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.
