    Thanks very much for clearing that up

    Images and Lenses (explanation needed please)

    Okay, so I have to do a Lab Report, easy enough, I've done them before, but it isn't so clear, and when I tried doing it, I wasn't sure if I was even doing it right. (Personal Note: DO NOT TAKE PHYSICS CORRESPONDANCE! ><) Anyway, here's what I have to do. The Lab Report is on the...

    Actual Depth and Apparent Depth

    Yay! Thanks so much! I really appreciate the help and for you putting up with my massive brain malfunction ^_^()

    Actual Depth and Apparent Depth

    *mutters something about incompitant calculators* So it should be something like this? \sin \theta_i = (n_i / n_R)\sin \theta_R = (1.00 / 1.33 )(\sin45*) = (0.7519)(0.7071) = 0.5317 \theta_i = 32.1*...

    Actual Depth and Apparent Depth

    gah what am I doing wrong? x.x

    Actual Depth and Apparent Depth

    0.8509 = \sin45* Or at least that is what I was doing...

    Actual Depth and Apparent Depth

    ooo I see, (forgot to put in an extra set of () ) so it should be: \sin \theta_i = (1.00/1.33) (0.8509) = 0.6398 \theta_i = 39.6* ??

    Actual Depth and Apparent Depth

    duh *slaps forhead* alright I have to rearrange the formula, I feel stupid now. So it should be: (ni)(sin{angle}i) = (nR)(sin{angle}R) so therefore sin{angle}i = (ni)/(nR)(sin{angle}R) ?

    Actual Depth and Apparent Depth

    okay, so I have to find the angle of incidence...so how do I do that? x.x

    Actual Depth and Apparent Depth

    Now I'm confused...how is d = 2.0m? if I did the equation for actual depth with that as d, it would mean the actual depth is the same as the apparent depth? Actual depth = (2.0m)/tan45* = (2.0m)/(1.0) = 2.0m

    Actual Depth and Apparent Depth

    I decided to give my brain a bit of a rest on this problem and moved forward. I think I may have it, I'd still like to see if it's accurate or get help if it's completely wrong (which is very likely) Here's what I have so far: Analysis: n[i] = 1.33 for water n[2]= 1.00 for air Actual...

    Actual Depth and Apparent Depth

    Okay, I need a bit of a jump start with this question, I know how to find the Apparent depth normally, but I've never done actual depth and I can't really figure it out (*stupid*) 11. Frederika is sitting in her fishing boat observing a rainbow trout swimming below the surface of the water...

    Calculating Wavelength in Water for Electromagnetic Radiation

    Seriously, if I didn't need physics I probably wouldn't take it.I've don the work for this one problem, but then I'm not sure if it's the right formula for what I need. Here's what I have so far(the parts in bold are the work I've done) 10. An electromagnetic radiation has a frequency of 5.00...
