4. WHAT IS WAVE MOTION ?????????

5. Wave motion is the
propagation of disturbance
from the point of medium to
other parts of it.

6. CHARACTERISTICS OF WAVE MOTION
 All types of traveling waves transport energy.
 Study of a single wave pulse shows that it is
begun with a vibration and is transmitted
through internal forces in the medium.
 Continuous waves start with vibrations, too. If
the vibration is SHM, then the wave will be
sinusoidal.

8. KINDS OF WAVES.

9. Longitudinal Wave
When a wave propagates through some
medium, if the local displacements of the
medium that constitute the disturbance are in the
direction of travel of the disturbance, then the
wave is longitudinal.
An example of a longitudinal wave is the
pulse that can be sent along a stretched slinky
by shaking one end of the slinky along its length.

11. Transverse Wave
A disturbance that is perpendicular to the
direction of travel are called transverse waves.
Examples are waves on strings, surface waves
on the water, etc.

13. (A) Longitudinal waves are created in a spring when the free end is moved back and
forth parallel to the spring.
(B) Transverse waves are created in a spring when the free end is moved up and
down.
