qus-(a) A incident wave is represented by: y=20 sin(2x-4t)
write the expression for reflected wave;-
1. from a rigid boundary
2.from an open boundary
(b) A particle is moving with S.H.M in a atraight line.
when the distance of the particle from the equilibrium position has values y1 & y2, the corresponding values of velocities are u1, u2. show that the time period of oscillation is given by;-
t= 2 pi root over{[(y2)power2-(y1)power2]%[(u2)power2-(u1)power2]}

what is the amplitude of a longitudinal wave....and how do we represent longitudinal wave graphically ...?
and i also want to know that how electromagnetic waves propogates in vaccum..how do they travel when there is no medium for oscillation...????
pls answer all my questions
