Speed of the waves is equal to:
Correct answer: C. Both A and B
- A. fλ
- B. λ/T
- C. Both A and B
- D. λT
Explanation
Explanation:The speed of a wave can be calculated using the formula: v = fλwhere v is the wave speed, f is the frequency of the wave, and λ is the wavelength of the wave.As we know that: f = 1/TSo, v = λ/TWhere T is the period of the wave.Hence the speed of the wave is equal to fλ and λ/T.

About Wave Speed
Wave speed is the rate at which a disturbance or wave pattern travels through a medium, given by v = fλ, where f is frequency and λ is wavelength. Questions examine how speed changes between media, the relation among frequency, wavelength and period, and why wave speed is not the same as particle vibration speed.
