A progressive wave of frequency 50 Hz is travelling with velocity 350 m/s through a medium. The change in phase at given time interval of 0.01s is

Options

  1. A4 , rad
  2. B2 , rad
  3. C, rad
  4. D3 2 , rad

Correct answer

C. , rad

Step-by-step solution

Given frequency f = 50 Hz Time interval t = 0.01 s The phase of a progressive wave at a fixed position varies with time as = t - kx + ₀ The change in phase over a time interval t is given by = t Since = 2 f , we have: = 2 f t Substituting the given values: = 2 50 0.01 = 100 0.01 = rad Answer: , rad
