NEET Physics Wave Motion MCQ Question
Which of the following statements about wave motion is correct?
The wavelength of a wave can be determined from the angular wave number using the relationship λ = 2π/k.
The speed of a wave is independent of the medium through which it travels.
A wave traveling in the positive direction can be represented by the equation y(x,t) = a sin(kx + wt).
The displacement of a wave at a fixed location varies linearly with time.
Correct Answer
Detailed Explanation
The wavelength is related to the angular wave number by the equation λ = 2π/k, as stated in the context. Option B is incorrect because wave speed depends on the medium. Option C incorrectly describes a wave traveling in the negative direction. Option D misrepresents the nature of wave displacement, which varies sinusoidally with time.
