3 cards from this section. Quick, good the night before a test.
What defines a transverse wave?
Consider the direction of motion versus displacement.
What does the wave speed depend on?
Think of the formula for wave speed.
What is a transverse wave?
Think about how a string is influenced when disturbed.
True or False: The wave speed in a string is independent of the tension?
Revisit the wave speed formula.
A string of length 2 m is fixed at both ends with a tension of 50 N. Calculate the wave speed if the mass per unit length is 0.25 kg/m.
Remember to apply the wave speed formula correctly.
Explain how varying the tension in a string affects both wave speed and wave frequency, using the wave equation to support your answer.
Use relationships between frequency, wavelength, and speed.
