MathJax(?): Can't find handler for document MathJax(?): Can't find handler for document This is basically a Single slit diffraction experiment.
d = width of the aperture or slit =0.1 mm=0.01 cm
L=distance between the aperture and the screen = 93cm
We know:
β = λ L d λ = 0.01 × .5 93 = 0.000053763 c m = 5.3763 × 10 5 c m = 5376.3   Awhere β = 5 m m (the distance between the central fringeand first fringe)
The wavelength of light source used is 5376.3 Angstroms

Currently I have a gas with a density that follows and inverse square law in distance, r. Given that I know the mass attenuation coefficient of this gas, I wish to calculate an effective optical depth using a modified version of the Beer-Lambert Law that uses mass attenuation coefficients:
τ = α ρ g a s ( T ) l ρ = α M p ( T ) ρ R T 1 x 2 d x
Where α is the mass attenuation coefficient for the solid phase of the gas [cm 1 ], ρ is the mass density of the solid phase of the gas, l is the path length, M is the molar mass of the gas, p ( T )is the pressure of the gas as a function of temperature, R is the ideal gas constant and T is the temperature of the gas. ρ g a s is the mass density of the gas itself and can be extracted from the ideal gas law:
ρ g a s = p ( T ) M R T
The integral emerges from my attempt at rewriting the first equation for a non uniform attenuation, that I have here due to the inverse square law effecting the density of the gas.
However, I am now concerned that units no longer balance here since τ should be unitless. Can anyone help guide me here?

Assume I have some contact eye lenses which I covered with black color, so they're not transparent anymore. Then I made a tiny hole at the center of each eye lens. What kind of an image will I see if I put them on? Will it be upside-down image like camera obscura does?
