NEET Physics Wave Motion MCQ Question
A harmonic wave is described by y(x, t) = a sin(kx - ωt). Based on the wave equation and Figure 14.6, which parameter does the symbol 'k' represent and what is its significance?
Angular wave number, relates to wavelength.
Angular frequency, relates to wave speed.
Amplitude, relates to wave energy.
Phase constant, determines initial phase.
Correct Answer
Detailed Explanation
In the given wave equation, 'k' represents the angular wave number which is connected to the wavelength of the wave as shown in the NCERT context. It is a measure of how many wave cycles exist per unit distance.
