580 nm light shines on a double slit with d=0.000125m. what is the angle of the first dark interference minimum(m=1)? Please help me. I has rewatched so many tutorials on how to do this but i keep getting the answer wrong! I keep getting 0.119 degrees, and that is incorrect. Please help..

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

i wanna say it’s between b and d, leaning more towards b.

measure their densities same density, same sub

d) physical means can be used to separate the components of air.
