STANDARD Physics Progressive Waves MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A progressive wave is represented by y = 5sin (100πt − 2πx) where x and y are in m and t is in s. The maximum particle velocity is
A
100π m s⁻¹
B
200π m s⁻¹
C
400π m s⁻¹
D
500π m s⁻¹
Correct Answer
Option D
Detailed Explanation
The given progressive wave is y = 5 sin(100πt − 2πx). The particle velocity is given by the derivative dy/dt = 500πcos(100πt − 2πx). The maximum particle velocity is 500π m s⁻¹.
