if superman really had x-ray vision at 0.12nm wavelength and a 4.3mm pupil diameter,at what maximum altitude could he distinguish villains from heroes, assuming the minimum detail required was 4.8cm?
Optics
in a interference expriment in a large ripple tank the coherent vibrating source are placed 120mm apart. the distance between maxima 2.0m away is 180mm .if the speed of ripple is 25 cm/s calculate the frequency of the vibrating source.

Why the full width at half maximum of the transmission peaks varies as the wavelength change ?
Optics
A grating is 2.6 cm wide. A spectral line of wavelength 439 nm is observed at 41 degrees in order 1. (The order # refers to a specific bright spot. The 1st bright spot right or left of the center in the 1st order bright spot. The 2nd, is the 2nd order bright spot.)
The grating is made up of how many lines?

why does light not harm us while it's speed is so large?
Optics
I need to test the resolution of a laser diode imaging system. According to modeling, the resolution is 4.4 micrometers. I need to test the resolution, however, I must maintain the 10 degree divergence angle and no emitters exist with a emitting area less than 4.4 micrometers and a divergence angle of 10 degrees. A pinhole or slit will cause diffraction changing the divergence angle.
