PHY 104 Wave and sound Objective Question
Take CBT

Question

In the general wave equation y = A sin(kx - ωt), what does the argument (kx - ωt) represent?
Options
A The amplitude of the wave
B The angular frequency of the wave
C The phase of the wave
Correct Answer
D The wavelength of the wave
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 2 states: 'You will then see that the argument of sine is the phase. If we write z = Asin(ωt + φ), the phase is ωt + φ.' In the given equation y = Asin(kx - ωt), (kx - ωt) is the phase.

Hint

This term determines the specific point in the wave cycle at a given position and time.
