A WAVE IS A DISTURBANCE WHICH PROPAGATES ENERGY FROM ONE
PLACE TO THE OTHER WITHOUT THE TRANSPORT OF MATTER.IT IS A ILL
SPREAD OVER A REGION OF SPACE WITHOUT CLEAR CUT BOUNDARIES.IT
CANNOT BE SAID TO BE LOCALISED HERE OR THERE.FOR PROPAGATION OF WAVE THERE ARE TWO PROPERTIS IN MEDIUM:
1)ELASTCITY
2)INERTIA
#TYPES OF WAVES:
MECHANICAL AND ELECTROMAGNETIC WAVES:
A WAVE MAY OR MAY NOT REQUIRE MEDIUM FOR ITS PROPAGATION.THE WAVES WHICH DO NOT REQUIRE MEDIUM FOR THEIR PROPAGATION ARE CALLED NON-MECHANICAL,e.g.,LIGHT,HEAT AND RADIO WAVES ARE NON-MECHANICAL AS THEY CAN PROPAGATE THROUGH VACUUM.IN FACT ALL ELECTROMAGNETIC WAVES ARE NON-MECHANICAL.
