I can't find my old book but what is the formula for the angular frequency of a light wave by wave length and phase velocity. I can't remember but it's simple.. Can't find it but I am sure I am looking in the wrong place |

02 May 15 - 02:04 AM (#3705851) Subject: RE: BS: Physics help From: olddude Of course as soon as I ask i find it online.. Thanks anyway |

02 May 15 - 02:46 AM (#3705855) Subject: RE: BS: Physics help From: Musket Frequency is velocity divided by wavelength. I recall that much. When I had a quick look online, it took me back a bit.. I never had to work with light but mechanical vibration used to be what put meat on my table and in a rather odd way, the formulae were somewhat nostalgic. To be honest Dan, I was wondering if you were devising some high tech fishing device! |

02 May 15 - 09:58 AM (#3705912) Subject: RE: BS: Physics help From: GUEST,# I was wrong. Found the following in the Urban Dictionary. "the angle of the dangle is inversely proportional to the heat of the meat, provided that the maxis of the axis, and the gravity of the cavity, remain constant." |

02 May 15 - 11:10 AM (#3705925) Subject: RE: BS: Physics help From: Ed T ""For a smart material to be able to send out a more complex signal it needs to be nonlinear. If you hit a tuning fork twice as hard it will ring twice as loud but still at the same frequency. That's a linear response. If you hit a person twice as hard they're unlikely just to shout twice as loud. That property lets you learn more about the person than the tuning fork". Neil Gershenfeld |

02 May 15 - 01:10 PM (#3705940) Subject: RE: BS: Physics help From: gnu No no no! The angle of the dangle is equal to the mass of the ass times the square of the hair. Where the hell did you go to school? |

But I don't care what they say. If you are having sinus problems, Dan, see a GP and keep away from that radiation. |

03 May 15 - 11:37 PM (#3706255) Subject: RE: BS: Physics help From: olddude The most general form of a harmonic wave is given by ψ = A cos[k(x - vt)] , where v is the phase velocity and k is the wave number. Expanding this we have ψ = A cos(kx - kvt) . We know that the argument of the cosine must be dimensionless, so the expression kvt must be dimensionless, thus kv must be an inverse time, or the angular frequency of the wave (we know it is an angular frequency and not a regular frequency since we want the argument of the cosine to be in radians, which are dimensionless). Thus σ = kv . But the wavenumber is just k = 2Π/λ But you can simply it further. This is what I needed |

04 May 15 - 10:27 AM (#3706350) Subject: RE: BS: Physics help From: GUEST,leeneia Now, all we are talking about is a wave, either of sound or light. It's moving evenly (sinusoidally) up and down. It occurs to me that theology and science differ in an important way. Theology makes the ineffable seem simple, and science makes the simple seem complicated. |
