Which harmonic frequencies can be detected in a tube closed at one end whose fundamental frequency is 200 Hz?
200 Hz
300 Hz
400 Hz
600 Hz
1000 Hz
In a tube closed at one end, the harmonic frequencies that can be detected are odd-numbered multiples of the fundamental frequency.
So, the harmonic frequencies that can be detected in this tube are:
200 Hz (Fundamental frequency)
400 Hz (2nd harmonic)
600 Hz (3rd harmonic)
800 Hz (4th harmonic)
1000 Hz (5th harmonic)
Therefore, the correct answer is:
200 Hz, 400 Hz, 600 Hz, 800 Hz, 1000 Hz.
