What if we send a bunch of pulses down the spring and let them reflect back?

How will they interfere with one another?

Go see what actually happens.


Standing wave them reflect back? – a wave that remains in a constant position

Formation:

  • Incident pulses are reflected

  • Reflections interfere with incident pulses

  • If points of constructive and destructive interference don’t move, a standing wave forms.

Period: the time it takes to complete one cycle. on the spring?

  • If a student oscillates a wave with a frequency of 5 cycles per second…

    • What is the frequency?

    • How long does it take to complete one cycle?

  • If one cycle is 4 seconds…

    • What is the frequency?

    • What is the period?


How are frequency and period connected? on the spring?

and

  • They are inverses of each other.
