Question
The gravitational acceleration on the moon’s surface is significantly lower than that of Earth’s at 1.62 m/s2 . Imagine physics students on a lunar colony are conducting a virtual copy of your standing wave using a 0.70m string with a linear density of 0.80 kg/m. They create a standing wave with 6 antinodes with a frequency of 1190 Hz. Now they switch strings, keeping the string length the same as before. If the students need a frequency of 278 Hz to again create a standing wave with 6 antinodes, what must be the linear density of the new string?
Explanation / Answer
When wavelenghth is same frequency is proportional to - (linear density) ^-0.5
New density = 0.3867 kg/m
