8. Reflection from a soap bubble film (n = 1.42) of thickness 106 nm
results in a constructive interference in the reflected light if this
film is illuminated by a beam of light with a wavelength of 601
nm. What are the next three thicknesses of this film that will also
result in a constructive interference?
a) 318 nm, 530 nm, 742 nm
b) 212 nm, 424 nm, 636 nm
c) 53.0 nm, 35.3 nm, 26.5 nm
d) 212 nm, 318 nm, 424 nm
e) 67.0 nm, 42.4 nm, 22.3 nm
