Wave and formation of waves with examples.|Sindh board| |Class 10| |new book physics| L-01

@WAVE:
Method transport energy from one point to another point without transfer of matter is called wave.


@FORMATION OF WAVES:
Disturbance of medium cause of formation of wave


Waves can be produce by using
1.Rope
2.slinky spring
3.Water waves in ripple tank


WAVES BY ROPE

-Consider waves of a rope by attaching one end of rope to a wall.

-Continuously moving the other end up and down.

-These up and down movements produce oscillations or vibrations.

-Now we can observe that waves travel towards the wall, whereas the rope itself moves only up and down.

-The rope is the medium through which the waves travel or propagate.

-Hence waves are the means of energy transfer without matter.



Q01.Waves are the means of energy transfer without matter. Justify this statement with the help of everyday life examples
