Question

1. A stone is thrown into a pond. What happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? Explain.

2. An athlete of average size is hanging from the end of a 20 m long rope, which has a mass of 4 kg and is attached to a hook in the ceiling of a gym. If the athlete makes a sudden movement at the end of the rope, estimate how long it will take the disturbance to reach the hook.

3. If the speed of sound depended on frequency, what problems would this create for live concerts?

Thank you ahead of time!!!

Explanation / Answer

1) as the wave was moving away from the point of disturbance,it carries the energy from one place to another place,hence amplitude of the resulting waves decreases as they get her from the point where the stone hit the water

2) T = 2*pi*sqrt(l/g) = 2*3.142*sqrt(20/9.81) = 8.97 s = 9 s

3) velocity v = lamda*f

for live concerts,the speed of air also influences the frequency of particles
