What type of wave involves motion perpendicular to wave direction?
Think of how particles move in a string.
Name an example of a longitudinal wave.
Consider how sound travels through air.
What distinguishes transverse waves from longitudinal waves?
Consider how each wave type moves relative to the direction of propagation.
True or False: Longitudinal waves require a solid medium to propagate.
Recall the medium types each wave requires.
A string and a slinky are both creating waves. If the tension in the string increases and the mass per unit length stays the same, what happens to the speed of the transverse wave in the string?
Use the formula for wave speed on a string.
Describe a scenario outside physics where the concept of waves can be observed and discuss the types of waves involved.
Identify the elements of crowd dynamics that showcase wave principles.
