1.at the first harmonic only
2.at the first and third harmonics
3.at the second and fourth harmonics
4.at the first and second harmonics

Question 2

Within a standing wave on a string,
1.all points along the string that oscillate do so within a range of different frequencies and amplitudes.
2.all points along the string that oscillate do so at the same frequency but within a range of different amplitudes.
3.all points along the string that oscillate do so within a range of different frequencies but at the same amplitude.
4.all points along the string that oscillate do so at the same frequency and amplitude.
