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?)

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

2. mike

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