NEET Physics Standing Waves MCQ Question
A string 2.0 m long and fixed at its end is driven by a 240 Hz vibrator. The string vibrates in its third harmonic mode. The speed of the wave and its fundamental frequency is-
320 m/s, 120 Hz
180 m/s, 80 Hz
180 m/s, 120 Hz
320 m/s, 80 Hz
Correct Answer
Detailed Explanation
The speed of the wave is calculated using the frequency and wavelength. The fundamental frequency is determined by the length of the string and the speed of the wave.
