Question 6
The sound waves emitted by three sources A, B and C are represented in Fig. 10.31. If the frequency of A is maximum and C is minimum, identify the corresponding curves, and mark A, B and C on them.
View Answer Hide Answer
  • Highest frequency (A) = curve with crests closest together (shortest wavelength).
  • Lowest frequency (C) = curve with crests farthest apart (longest wavelength); B is in between.
Marking A, B and C A: highest frequency, crests closest C: lowest frequency, crests farthest B lies in between
Back to: 10.6.1 Wavelength, frequency and time period
