AIPMT PRELIMS 2006 Physics Wave Speed MCQ Question
Type: MCQ-numerical-Medium-Class 11
A transverse wave propagating along x-axis is represented by: y(x, t) = 8.0 sin (0.5πx - 4πt - (π/4)) where x is in metres and t is in seconds. The speed of the wave is:
A
8π m/s
B
0.5π m/s
C
(π/4) m/s
D
8 m/s
Correct Answer
Option D
Detailed Explanation
The wave speed v is given by the coefficient of t in the wave equation, which is 4π. Thus, v = 8 m/s.
