Finding the total vertical distance - transverse wave

Click For Summary
SUMMARY

The discussion focuses on calculating the total vertical distance a colored dot moves in a transverse wave with an amplitude of 5.89 cm and a frequency of 5.00 Hz over a period of 3.00 seconds. The initial attempt incorrectly calculated the displacement as zero, due to misunderstanding the difference between displacement and total distance traveled. The correct approach involves recognizing that the dot completes several oscillations, thus the total vertical distance is the product of the amplitude and the number of oscillations within the given time frame.

PREREQUISITES
  • Understanding of transverse wave properties, including amplitude and frequency.
  • Familiarity with wave equations, specifically y = A sin (2πft).
  • Knowledge of oscillation concepts and how to calculate total distance from amplitude.
  • Basic grasp of time-frequency relationships in wave motion.
NEXT STEPS
  • Calculate total vertical distance for different amplitudes and frequencies in transverse waves.
  • Explore the relationship between frequency, period, and oscillation count.
  • Learn about wave motion and energy transfer in transverse waves.
  • Investigate the implications of amplitude changes on total distance traveled in wave mechanics.
USEFUL FOR

Students studying physics, particularly those focusing on wave mechanics, as well as educators seeking to clarify concepts of displacement versus total distance in oscillatory motion.

Homework Statement



Suppose the amplitude and frequency of the transverse wave in the figure are, respectively, 5.89 cm and 5.00 Hz. Find the total vertical distance (in cm) through which the colored dot moves in 3.00 s.

Homework Equations



y = A sin (2pi x f x t - (2pi x)/λ)
v=λf
v= x/t

The Attempt at a Solution



x=vt
λ=v/f

x/λ = vt/ (v/f) = t x f = 15

Plug in x/λ = 15
Plug in A = .0589m
Plug in f = 5 Hz
Plug in t = 3.00 seconds

Answer = 0m

However, the online system says it is incorrect. I have no other strategy besides this one? Can someone help?

You have found the displacement. Which is zero, because in 3.00 seconds the dot makes a few COMPLETE oscillations and returns where it was. You need to find the distance, which is the length of the total path the dot has gone through.
 
OH
y = displacement and not distance! Got it.

Thanks so much!
