if you have frequency of 440 then what is the wavelength

Question

xishem · Answer

The wave-speed equation relates the frequency and wavelength of an equation:$$s=\lambda\nu$$Where s is the propagation speed of the wave, lambda is the wavelength, and nu is the frequency.

xishem · Answer

In other words, it depends what the propagation speed of the wave is.

anonymous · Answer

We know  that,velocity=wavelength*frequency. here wavelength=velocity/frequency=3*10000000000cm/sec/440cycles/second=0.068*1000000000cm/cycles

xishem · Answer

The problem doesn't specify that it's a wave of light — if it were, 440Hz is an incredibly low frequency for a light wave, and that's why I'm partially detracted from just assuming that it is light.

I think that in music the note A (above middle C) has  frequency   $\nu=440 [\text{Hz}]$
the speed of sound in air is about   $s=340 [\text m/\text s]$

Use the wave-speed equation Xishem has provided, 

first rearrange it, to solve for $\lambda$ (the wavelength)

then just substitute in frequency and speed

to get the units to simplify, use the fact that hertz are inverse seconds   $[\text{Hz}]\equiv [\frac1{\text s}]$

A440 is the musical note A above middle C.  It has a frequency of 440 Hz and is a general tuning standard for musical pitch.  So you would use the speed of sound in air which is given by 

speed = 331.4 + 0.6*Temp
      = 343.6 m/s at 20 deg C

Lamda = speed / frequency
      = 343.6 / 440
      = 0.78 meters
