450 nm light is incident on two parallel glass plates (n=1.5) with air (n=1) between them. A) What minimum thickness gap will result in constructive interference? B) What minimum thickness gap will result in destructive interference? Al = (4) + 2+2tn + 2tn Constructive (bright) Ac=m Destructive (dark) Ac=(m+1) 450 nm light is incident on two parallel glass plates (n=1.5) with air (n=1) between them.
