@tr.mwambi: A soap bubble creates its own rainbow through the physics of light.When white light reflects off the bubble’s two surfaces, the reflected waves interfere. Some wavelengths reinforce each other while others cancel out, making certain colours visible.For constructive interference in a soap film surrounded by air, 2nt cos(θ) = (m + 1/2)λ, where t is the film thickness and λ is the wavelength.As the film gets thinner or thicker, the colours change. The rainbow isn’t a pigment. #physics #foryou
