If the frequency of a sound wave is doubled then the velocity of sound will be
If the frequency of a sound wave is doubled then the velocity of sound will be
- A. zero
- B. half
- C. double
- D. unchanged
Step-by-step solution
The velocity of sound in a medium is determined by the medium's properties (e.g., density, elasticity, temperature) and is independent of frequency. According to the wave equation v = fλ, if frequency doubles, wavelength halves to keep velocity constant. Thus, the velocity remains unchanged.
