Question Description
I’m working on a physics multi-part question and need support to help me understand better.
An electric oscillator of adjustable frequency drives the string as shown in Fig. 3
|
mass of string (kg) |
oscillation length (m) |
total length (m) |
Weight creates tension (kg) |
|
0.00098 |
6.000 |
6.427 |
0.262 |
(a) Find frequency of the oscillator when there are four loops of standing waves along L and the traveling wave equations (amplitude A=2.00 cm).
(b) If density of the string doubled but frequency remains the same, find the positions of the nodes along L.
(c) When frequency and density remain as (1), find the new weight that would induce ten loops of standing waves.
