1 questions with worked solutions.
Q1. If the frequency of a sound wave is doubled then the velocity of sound will be
Answer: unchanged
For sound in a fixed medium, the speed depends on the properties of the medium (like elasticity and density), not on frequency. If the frequency doubles, the wavelength halves so that v = fλ stays the same.
