Q14.9: NCERT Physics - Part 2 WAVES 14.9 Solution: For the wave described in Exercise 14.8, plot the displacement…
For the wave described in Exercise 14.8, plot the displacement (y) versus (t) graphs for x = 0, 2 and 4 cm. What are the shapes of these graphs? In which aspects does the oscillatory motion in travelling wave differ from one point to another: amplitude, frequency or phase?
Step-by-Step Verified Solution
**Answer:** The graphs are sinusoidal. All points have the same amplitude and frequency but different phases.
**Step-by-Step Explanation:**
For a travelling wave, each point on the string oscillates with the same amplitude and frequency. However, the phase of oscillation depends on the position . The displacement-time graphs for different are sinusoidal with the same amplitude and frequency but shifted in time (phase difference) .
