A String with a Fixed Frequency Vibrator at One End

question 56

Multiple Choice

A string with a fixed frequency vibrator at one end is undergoing resonance with 4 antinodes when under tension T₁. When the tension is slowly increased the resonance condition disappears until tension T₂ is reached, there being no resonances occurring between these two tensions. How many antinodes are there in this new resonance?

• A) 3
• B) 4, since all resonances in this situation have the same number of nodes
• C) 5
• D) 2, since resonances only involve whole wavelengths
• E) 6, since resonances only involve whole wavelength
