Thin film interference
Thin film interference on soap film. Bands of colour are created by white light shining on a film of soap. Some of the light reflects off the surface of the film, while the rest of the light travels through the film and reflects off the back of the film. The reflected light waves interfere with each other, either constructively (coloured bands) or destructively (black bands). Different colours are seen due to varying film thickness and viewing angles

EDITORS COMMENTS
This print captures the mesmerizing phenomenon of thin film interference on a soap film. As white light illuminates the delicate film, bands of vibrant colors come to life, creating a stunning visual display. The intricate pattern is formed as some of the light reflects off the surface of the film, while the remaining light travels through and reflects off its back. The magic lies in how these reflected light waves interact with each other - they either constructively or destructively interfere. This interference gives rise to alternating colored bands and black regions within them. The varying thicknesses of the soap film and different viewing angles contribute to this kaleidoscope of hues that dance before our eyes. This image not only showcases an enchanting optical effect but also serves as a testament to scientific exploration. It represents an experiment delving into physical properties such as wave behavior and optics, shedding light on fundamental principles in physics. As we gaze upon this photograph, we are reminded of nature's ability to create breathtaking displays through simple yet profound phenomena. It invites us to appreciate both the beauty found in everyday objects like soap films and the wonders hidden within science itself.
