NEET Physics Wave Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
A wave is traveling along the positive x-axis and is described by the equation y(x, t) = a sin(kx - ωt). If the wavelength of the wave is 2 meters, what is the angular wave number k?
A
π rad/m
B
2π rad/m
C
π/2 rad/m
D
1 rad/m
Correct Answer
Option A
Detailed Explanation
The angular wave number k is given by the formula k = 2π/λ. Given that λ = 2 meters, substituting this into the formula yields k = π rad/m.
