Finding wavelength with just frequency?

One radio station in the middle of the FM band has a frequency of 95.0 MHz. What is its wavelength?



lambda=v/f



I assume that the velocity of the wave is 343 m/s. I convert 95MHz to Hz, which is 95,000,000 Hz.
lambda=(343 m/s) / 95,000,000 Hz.
I come up with 3.51e-6.
Webassign, being a big jerk, marks it wrong.
What am i dong wrong =(
I tried dividing by 95 MHz anyway just to see, and that was wrong as well.
Thanks in advance for your guys' help! =)

Your approach looks right. I got 3.61e-6 so maybe your program is sensitive to that

Radio refers to electomagnetic waves, which propagate at the speed of light, which is the speed of the wave in this question.

Yeah...i was about to delete this forum topic becuase i finally found the same problem in an earlier assignment.
I'd have to use the speed of light and divide the Hz. xD Woops.
Thanks guys =)
