A periodic wave can be mathematically written as y = A sin (kx- \omegat)
1. What part of the wave does A explain?
2. If we take a snapshot of the wave, what s the distance among two crests (or troughs) called? How is this related to k?
3. The source that is generating the wave oscillates by a frequency of f. How is this related to \omega?
4. Write down the relationship among wave speed, wave frequency and wavelength?
