Make the same observation of wave speed - the speed of the crest moving from left to right across the screen. Does this ten-fold increase in frequency - from
about 0.1 Hz to about 10 Hz - have any noticeable and appreciable effect upon the wave speed? Explain
your answer and discuss your observations.

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

could you add the photo?
