Longitudinal and Transverse Waves

 LONGITUDINAL WAVES

The waves in which the particles of a medium vibrate in the  direction of propagation of wave are called a longitudinal wave.

These waves propagate in the form of compressions and rarefactions.

Example: Sound waves in air.


TRANSVERSE WAVES

The waves in which the particles particles of a medium vibrate in the direction perpendicular to the direction of propagation of waves are called transverse waves.

These waves propagate in the form of Crests and troughs 

Example: water ripples

UNIFORM CIRCULAR MOTION

In uniform circular motion,  1. Speed is constant. 2. Velocity is variable and acts along tangential direction  at a point. 3. Centripetal Force and acceleration act along the radius towards the centre if the circular path.  4. Centrifugal force appears to  act radially outwards. It is a virtual  ,fictitious force, not a real force.

ECHO IN LIVING ROOM

Why is echo not heard in our living rooms? To hear echo, the minimum distance between the source and the reflector must be 17m. When this distance is more than 17m, the reflected sound can be distinguished from the original. As the length of our rooms is less than 17m, we don't hear echo.
