How would I go about calculating wavelength and frequency?

OpenStudy (ipwnbunnies):

There's a few ways...If you know the energy \[E = \frac{hc}{\lambda} = hf\] Where 'h' is Planck's Constant, 'c' is the speed of light (if it is light)

OpenStudy (anonymous):

I should have been more specific. It's referring to like gamma waves and stuff. O.o I don't remember the exact question but it was something to the effect of "if a segment of a wave is 10m, and the wavelength if 5 times less than that, calculate the frequency and wavelength." Again, I don't remember the exact wording but it was something like that.

OpenStudy (ipwnbunnies):

So...the wavelength is 10m/5 = 2m? That's not a gamma ray. Maybe I'm getting confused now :3

OpenStudy (anonymous):

I came across this on Yahoo Answers. O.o λ=v/f

OpenStudy (ipwnbunnies):

Yeah, that's another formula. \[v = f \lambda\] The speed of a wave = freq*wavelength

OpenStudy (anonymous):

What are the units on this?

OpenStudy (ipwnbunnies):

f in hertz, or 1/s and wavelength in meters. So speed is in m/s

OpenStudy (anonymous):

Wouldn't all waves travel at the same speed though? 299,792,458 meters per second?

OpenStudy (ipwnbunnies):

No, that's just light in a vacuum. The equation can be used for sound too.

OpenStudy (anonymous):

xD I don't think xrays have a sound, man.

OpenStudy (ipwnbunnies):

Xrays are a form of light.

OpenStudy (ipwnbunnies):

Sounds is about a million times slower than light lol

OpenStudy (anonymous):

Yes, I know. c: I'm kidding. I haven't taken physics yet but I have a physics book. Just don't feel like reading all of it again. ._. at least I was right about xrays and gamma rays being the fastest. It was on an ACT pretest thing that literally took me four hours. I'm not even done with the science part. The school said that it didn't really matter, so I mean I'd like to at least have the equation to figure out the speed of the wave or whatever the question was asking. v_v

OpenStudy (ipwnbunnies):

Lol, I see man. Good luck with everything then.
