The initals "Am" stand for amplitude modulation. Insted of fluctuating frequenices as above, they instead vary the amplitude, such that Y= A(t) sin [2pief]t. Notice that the frequency is now fixed, but the amplitude will be inconsistent. Each AM station is assigned a frequency in KHz (1,000 waves/second.) For example, 760AM is assigned a frequency of f=760kHz. What is the wavelength of the 760AM radio waves? Sketch of graph of y=2(exponent t) sin(t) and explain graphically what the amplitude is doing. The Bay of Fundy is between Maine and Nova Scotia, and it is famous for its high tides. There is a dock such that the water is 2ft deep at low tide and 58ft deep at high tide. High tide occurs 6 hours and 12 minutes after low tide. Draw a graph and create the equation that models that depth of water nd a function of time after high tide has occurred.
