tunnfilminterferens
Tunnfilminterferens refers to the phenomenon where light waves reflected from the top and bottom surfaces of a thin film interfere with each other. This interference can be either constructive or destructive, depending on the thickness of the film and the wavelength of the light. When constructive interference occurs, certain wavelengths of light are amplified, leading to the appearance of vibrant colors. When destructive interference occurs, certain wavelengths are canceled out, making them less visible.
This effect is commonly observed in everyday situations. For example, the iridescent colors seen on soap bubbles
The angle at which light strikes the film also plays a role in the observed interference patterns.
