The wavelength of a wave traveling with a velocity of 420 ms-1 is 42 m. what is its period?
Answer Details
The formula for the speed of a wave is given by v = λ/T, where v is the velocity, λ is the wavelength, and T is the period. We are given that the velocity is 420 m/s and the wavelength is 42 m. We can use these values to solve for the period. Rearranging the formula, we get: T = λ/v Substituting the given values, we get: T = 42 m / 420 m/s Simplifying, we get: T = 0.1 s Therefore, the period of the wave is 0.1 seconds. Answer: 0.1 s
