- Homework Statement
- The headlights of a pickup truck are 1.15 m apart. What is the greatest distance at which these headlights can be resolved as separate points of light on a photograph taken with a camera whose aperture has a diameter of 13.5 mm? (Take wavelength = 531 nm.)
- Relevant Equations
- theta = 1.22*(wavelength)/(width of aperature0
I know that in order for the two lights to be distinguishable from one another they have to be separated by an angle of at least theta = 1.22(wavelength)/(width of aperture). I tried drawing the given picture below and then using trig to find L in terms of d/2 and theta/2. However, this ended up not being the right answer, so now I am confused as to what to do next. Am I solving this in the correct way or is there something I'm missing?
