    How Is Light Intensity Affected by Multiple Polarizing Filters?

    Consider the following polarization problem.The original light wave is completely un-polarized.The first screen is oriented vertically, while the last (third) screen is oriented horizontally. The middle screen is angled at 30° from the vertical. Assume the original intensity of the unpolarized...

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Awesome! Thanks a lot TSny, I appreciate the help. for b) I didn't know the formula but after looking around online, I found the equation a(central maximum)= 2Lλ/w a=2(1.7)(5.96*10-7) / 1.5*10-5 I got 0.13m = 13cm... Did I do it right?BTW, this isn't related to what you were helping me...

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    According to my notes it's the 4th minimum that's 27cm from the central line.. I was supposed to plug in 0.27m wasn't I...

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Ugh, so close to giving up on this one :p too tired.. I divided 4*1.5*10-5 by 4*1.7 and I got 8820nm.. is that correct?

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    after everything gets canceled out, should I only have X*w =λ? If so, I got 60000nm

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Since I'm bringing over n and L they would become negative on the left side correct?

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Divide both sides by n and L which would cause them to disappear?

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Could I move n and L to the other side of the equation?

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    You would get X*w= n*L*λ right?

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    by 1.5x10-5? So it should look like this then? (4)(1.5x10-5) = (4)(1.7)(1.5x10-5)λ

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Well for that I would just multiply the 4 and 2 to find x...Sorry, I misread. I'm a little tired. I just don't know how to rearrange this equation to find λ.

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    divide a by b to isolate x?

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Hey TSny, actually that is what I'm having trouble with. My brain is absolutely fried. It's probably so simple, but I can't seem to figure it out right now.

    Calculating Wavelength and Central Maximum Width Using Single Slit Equations

    Homework Statement A beam of light of unknown wavelength is incident on a screen with a single-slit. Observing the interference pattern on the projection screen that is 1.7 m away, the 4th minimum is 27 cm away from the central line. The width of the slit is 15 μm. a) What is the wavelength...
