1) Selena measures the total distance between the nodes on either end of a standing wave pattern to be 0.75 m, and she records that there were three antinodes between the endpoints. When she calculates half of the wavelength of the pattern, using these measurements, what is the result? Express your answer in meters.

4) Jerome has added mass to the holder and created the standing wave pattern. He observes that the string appears to have nodes where it meets the pulley and where it is attached to the fork. When performing step 7, he should

measure and record the distance between any two adjacent antinodes.

measure and record the distance between the two nodes that are nearest the pulley and fork, but not at the pulley and fork.

measure and record the distance between the two nodes that are nearest the pulley and fork.

  

measure and record the distance between any two adjacent nodes.

5)In this experiment, the standing wave pattern changes when more mass is added to the holder because

  

the frequency of the standing wave pattern changes.

   

the wavelength must remain the same for each standing wave pattern.

   

the product of frequency and wavelength must always be the same.

   

the velocity with which waves travel on the string changes.

A standing wave pattern is created on a string with mass density μ = 3 × 10-4 kg/m. A wave generator with frequency f = 63 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley is L = 0.68 m. Initially the 3rd harmonic wave pattern is formed....
