A wave is described by the equation
.
(A) Find the time period and the wavelength? (B) Write the equation for the velocity of the particles. Find the speed of the particle at x = 10 cm at time t = 001 s. (C) What are the speeds of the particles at x = 30 cm, 50 cm and 70 cm at t = 001 s?
(D) What are the speeds of the particles at x = 10 cm at t = 0011, 0012 and 0013 s?
A. 20 ms, 40 cm
Here
So, T=20ms
Again,
From the question,
B. zero
We know that
C. zero
For all x=(2n+1) and t=0.01s
D. 97 cm s−1, 18 cm s−1, 25 cm s−1
At t=0.011s
At t=0.012s
At t=0.013s
