Question 2
For a sound wave propagating in a medium, increasing its frequency will increase its (i) wavelength (ii) speed (iii) number of compressions per second (iv) time period
View Answer Hide Answer

Answer: (iii)

  • Higher frequency = more oscillations per second = more compressions per second .
  • Speed depends on the medium (unchanged); wavelength and time period decrease as frequency rises.
Raising the Frequency Frequency is compressions per second Higher frequency means more compressions per second Speed fixed; wavelength and period fall
