SUMMARY
The minimum thickness of a soap bubble required for colorful reflections is determined by the equation λ = 4nt, where λ represents the wavelength of light, n is the refractive index, and t is the thickness of the bubble. Given a refractive index of 1.33 for the soap bubble, the smallest wavelength of visible light (approximately 400 nm) should be used to calculate the minimum thickness. This results in a minimum thickness of approximately 0.133 mm for brightly-colored reflections to be observed.
