STANDARD Physics Waves on Strings MCQ Question
Type: MCQ-numerical-Medium-Class 11
A wire stretched between two rigid supports vibrates in its fundamental mode with a frequency of 50 Hz. The mass of the wire is 30 g and its linear density 4 x 10⁻² kg m⁻¹. The speed of the transverse wave at the string is
A
25 m s⁻¹
B
50 m s⁻¹
C
75 m s⁻¹
D
100 m s⁻¹
Correct Answer
Option C
Detailed Explanation
The speed of a wave on a string is given by v = √(T/μ), where T is the tension and μ is the linear density. For the fundamental mode, 2L = λ, and v = fλ. Substituting the given values, the speed of the transverse wave is 75 m s⁻¹.
