- If you finish before your classmates, go to Raise.me, update any info that has changed.
Guiding Questions:
You should work towards understanding the following by the end of this unit.
- How is simple harmonic motion connected to uniform circular motion?
- How can oscillatory motion be represented graphically and mathematically?
- How is conservation of energy applied in simple harmonic oscillators?
- How are waves energy transport phenomena?
- How do the relative velocities of the source of a wave and of the observer affect the frequency of the observed wave?
- How do waves from more than one source interfere to make waves of smaller or larger amplitude, depending on the location where the waves meet?
- How can wave boundary behavior be used to derive and apply relationships for calculating the characteristic frequencies for standing waves in strings, open pipes, and closed pipes?
Today:
Given: A spring, string, other commonly available materials
Show: That you and your partner(s) can demonstrate and explain
- the difference between the two types of mechanical waves - longitudinal and transverse.
- behavior of a wave that is reflected from a fixed-end boundary and a free-end boundary.
- behavior of a wave when it is reflected and transmitted from various boundaries (spring to string, different types of media, etc.).
