Question

Waves play an important role in our daily life. It is because
MOTION
waves are carriers of energy and information over large
distances. Waves require some oscillating or vibrating source
Here we demonstrate the production and propagation of
different waves with the help of vibratory motion of objects
Activity 10.1: Dip one end of a pencil into a tub of water, and
move it up and down vertically (Fig. 10.6). The disturbance in
the form of ripples produces water waves, which move away
from the source. When the wave reaches a small piece of cork
floating near the disturbance, it moves up and down about its
original position while the wave will travel outwards. The net
displacement of the cork is zero. The cork repeats its
vibratory motion about its mean position.
Hetivity 10.2: Take a rope and mark a point P on it. Tie one
end of the rope with a support and stretch the rope by
holding its other end in your hand (Fig. 10.7). Now, flipping
the rope up and down regularly will set up a wave in the rope
which will travel towards the fixed end. The point P on the
rope will start vibrating up and down as the wave passes
across it. The motion of point P will be perpendicular to the
direction of the motion of wave.​
