    Graduate Energy from proton and antiproton

    Is there a set wavelength for photons produced from antimatter reacting its matter equivalent, and if there is, what wavelength does a proton and antiproton reacting create?

    High School How is reflectivity of a surface determined?

    Oh. Actually I was wondering how you determine refractive index without testing. Sorry.

    Questions about Lasers: Maser Substance & Wavelength Determination

    There are two questions I wanted to ask. The first is what substances are used in a maser? The second is how can the wavelength of a laser using a certain substance be determined without physical testing?

    High School How is reflectivity of a surface determined?

    I have no real experience in this subject and wanted to ask, can the amount of reflection (in terms of electromagnetic waves) of a substance be determined without physical testing?

    Undergrad Does this equation already exist?

    Ok, then can anyone who's read something about this explain why cot(180/n)=tan(90(n-2)/n)?

    Undergrad Does this equation already exist?

    This is a formula to find the area of a regular polygon with sides of equal length only using the side length. (ns2cot(180/n))/4 Where n is equal to the number of sides and s is the side length. Also, knowing radius (r) or apothem (a) (na2tan(180/n))/4 (nr2sin(180/n)cos(180/n))/4...
