alleryStart learning →Velocity V, frequency f and wavelength of a wave are related as
AV = f times wavelength
BV = f plus wavelength
CV = f divided by wavelength
DV = wavelength divided by f
Answer & Solution
Correct answer: A. V = f times wavelength
1. The chapter gives the basic wave equation.
2. Velocity equals frequency multiplied by wavelength.
3. So V = f * lambda.
4. Hence option A is correct.
