This document provides an overview of waves, including definitions of transverse and longitudinal waves. Transverse waves transfer energy perpendicular to the direction of propagation and examples include light, radio, water, and sound waves. Longitudinal waves transfer energy parallel to propagation direction and examples are sound waves, waves in slink, and oscillations in springs. Key characteristics of transverse waves are defined as wavelength, crest, trough, and frequency.

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

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

6. 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.

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

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

9. Velocity of a wave = frequency of the wave * wavelength of the wave
