Wavelength and Frequency

Question 11 • Applications and Modeling

A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies:C - 262 HzE - 330 HzG - 392 HzDetermine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. (Due to rounding the ratio will be approximate.) How many E waves will fit in the length of four C waves?

Answer
A
2
B
3
C
4
D
5

Explanation

The frequency ratio of E to C is 330:262, which is approximately 5:4. Since wavelength is inversely proportional to frequency, E waves are shorter than C waves, so about five E waves fit into the length of four C waves. The correct choice is 5 waves.
