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

A wave on a string has a speed of 14 m/s and a period of 0.6 s.

Can any solve this question.
A uniform sinusoidal wave of wavelengths 0.871cm travel along a string. The time for a particular point to reach the maximum point or peak to the immediate zero point is 0.170s
1) what is the period?

2) what is the speed of the wave?
