chemistery question....please HELP!!!?

please dont pay attention to the first two answers...they are just being stupid...

here is the equation that you need:

Speed of the wave = Frequency x Wavelength

so, you need to know what the wavelength is, so you solve the equation above for wavelength which is:

wavelength= speed of the wave/frequency

now, you just plug in your values...

wavelength= 340/440

so wavelength= 0.773

i am preety sure that this is correct, so i would double check this...good luck and i hope this helped..:)

a website that might be helpful is...

http://eosweb.larc.nasa.gov/EDDOCS/wavelength.html

thats not chemistry, and Hz is the measure of a wavelength isnt it

learn to spell first.

chemistry...
