Determine the frequency of the note F4, 5 Seminotes above middle c (C4=261.6Hz) So would it be C4 = 261.6Hz x 1.05946^5 The fact they say semi notes is throwing me off, so I'm not sure if it's right.

**physics**

Oh wait I see, so then do you use the v=fx so solve for the frequency? Like 2.0x10^8 m/s = 7.0x10^-7 m f And then use that frequency to find the new wavelength?

**physics**

I don't understand. So is the 35s part not right? Because then you could plug it into the f=1/t formula.

**physics**

Ohh wait never mind. Would it be TIME = 7.0x10^-7 m / 2.0x10^8 m/s =35s And then you would plug it in as f=1/35s?
