Musicians need to be able to discern frequencies which are quite near each other. Assume that the average musician can differentiate between frequencies that vary by only 0.6%. This corresponds to about 1/10 of the frequency difference between neighboring notes in the middle of the piano keyboard.     Part (a) What is the closest lower frequency, in hertz, to 460 Hz that a musician can clearly distinguish as being different in frequency from 460 Hz?Numeric   : A numeric value is expected and not an expression.f- = __________________________________________Part (b) What is the closest higher frequency, in hertz, to 460 Hz that a musician can clearly distinguish as being different in frequency from 460 Hz?Numeric   : A numeric value is expected and not an expression.f+ = __________________________________________

Seiche

A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
