STANDARD Physics Simple Harmonic Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
The equation of a simple harmonic wave is given by y = 5 sin(π/2 (100t - x)), where x and y are in metre and time is in second. The time period of the wave (in seconds) will be:
A
0.04
B
0.01
C
1
D
5
Correct Answer
Option A
Detailed Explanation
The angular frequency ω = 2π/T = π/2 × 100. Solving for T gives T = 2/50 = 0.04 seconds.
