A wave has a speed of 340m/s and a period of 0.28ms. what's the wavelength?

so I worked this and I got 95.2m but the answer to d question says 0.095m.

period(T) = 1/F (since F = 1/T)
therefore, F = 1/0.28 = 3.5714
wavelength = velocity/frequency
w = 340/3.5714 = 95.2m (Isn't dis correct?)

  • physics(waves) -

    You multiplied by 0.28s, but the period is 0.28 ms.

  • physics(waves) -

    convert your milliseconds 0.28 into seconds first then do as you done. Converting will give you .28x10^-3
