The two points of a medium are separated through a distance of 10 cm. What is the phase angle between these two points if the wavelength of the wave is 0.1m?
Correct answer: B. 2π
- A. π
- B. 2π
- C. 3π
- D. 3π/4
Explanation
The phase angle between two points on a wave can be calculated using the formula: phase angle = (2π/λ) * (distance between the two points) where λ is the wavelength of the wave. Substituting the given values, we get: phase angle = (2π/0.1) 0.1 = 2π The other options are incorrect because of different values.

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.
