What is the wavelength of the wave if the phase angle between two points of the medium is 3π/4 and they are separated through a distance of 3 cm?
Correct answer: A. 8 cm
- A. 8 cm
- B. 9 cm
- C. 1 cm
- D. 12 cm
Explanation
Δθ= 2π(ΔS)/λ λ = 2π(ΔS)/Δθ = 2π (3* 10-2)/3π/4 = 4*2*10-2 = 8cm

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.
