The phase angle between two points in a medium is 4 pi/5. What is the separation between these two points if the wavelength of the wave is 5 m?
Correct answer: C. 2m
- A. 5/4 m
- B. 4pi m
- C. 2m
- D. 10m
Explanation
SOLVE AS follows: Given that the phase difference is 5, For the minimum difference in length between the points, assume they lie within the same wavelength.For a length difference of 2, the phase difference was 2πFor a length difference of x, the phase difference was 5. We find 'x' to be 10 .Given that the wavelength is 0.5m.In other words, x is 5cm.

About Progressive Waves
Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
