Light of $690-\mathrm{nm}$ wavelength interferes constructively when reflected from a soap bubble having refractive index $1.33 .$ Determine two possible thicknesses of the soap bubble.
A soap bubble is 100 nm thick and illuminated by white light incident perpendicular to its surface. What wavelength of visible light is most constructively reflected, assuming the same index of refraction as water (n = 1.33)? Visible wavelength is between 380 nm and 760 nm. Answer: nm
