Homework Statement
I'm not sure what I'm messing up here:
"An American standard television picture is composed of about 485 horizontal lines of varying light intensity. Assume that your ability to resolve the lines is limited only by the Rayleigh criterion and that the pupils of your eyes are 5.13 mm in diameter. Calculate the ratio of minimum viewing distance to the vertical dimension of the picture such that you will not be able to resolve the lines. Assume that the average wavelength of the light coming from the screen is 570 nm."
Homework Equations
diameter of pupils = d = 5.13*10^-3 m
wavelength = r = 570 * 10^-9 m
Now I think I'm supposed to use this equation:
(theta) = 1.22 * (wavelength)/(Diameter)
The Attempt at a Solution
I'm not really sure where to go from here, and can't figure out how the 485 horizontal lines plays into this. Can someone guide me through this one? I've never had a problem in my homework like this before.
Thanks!
