Frequency Transparency

  1. Dec 3, 2008 #1
    I was wondering if someone could give me a formula/explanation in how to find out if a given frequency will travel through an object or some sort...

    I believe higher as well as longer wavelengths have better chances of going through something than the reverse. Any ideas??

    What information would you need from the object? Index of Refraction??

    It depends on the materialand frequency.

    For visible/infrared light and a transparent material you can work out the absorption frequncies from the bonds.

    For microwave/radio you can work out an approximation from the conductivity and material thickness.
