This is the derivation i found in a book:
"y1(x, t) = a sin (kx – ωt) [wave traveling in the positive direction of x-axis] ...(1)
and
y2(x, t) = a sin (kx + ωt) [wave traveling in the negative...
Consider a transverse sinusiodal wave on a sting. Let the wave be traveling in positive x-direction. Let its amplitude be A, wave no. be k and angular frequency be ω then the vertical displacement of any particle at a distance x from the origin and at any time t is given as:
y(x,t) = A...
Thanks sir! This has solved my problem. I solved it like this:
Let v1 be the velocity of the smaller mass wrt the ground when it just flies away from the larger mass. Taking 'the larger mass + smaller mass as the system' and applying law of cons. of energy, we have:
Intial energy = Final...
A small body of mass m placed over a larger mass M whose surface is horizontal near the smaller mass and gradually curves to become vertical. The smaller mass is pushed on the longer one at a speed v and the system is left to itself. Assume all surfaces to be frictionless. (Please refer the...
