The phase angle between two points is 3 pi. The distance between these points is 15 cm. What is the wavelength of the wave?
Correct answer: D. 10 cm
- A. 30 cm
- B. 45 cm
- C. 5 cm
- D. 10 cm
Explanation
According to the formula of Phase Difference ΔΦ=Δx(2pi/λ) where, ΔΦ = phase difference ( phase angle between two points ) λ = wavelength of wave Δx = path difference ( distance between two points on wave ) So, 3pi=15(2pi/λ) λ =2pi x 15/3pi=10cm

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.
