In a thin film of air between two glass plates, which of the following colors will be least affected by interference? (2022)
Step 1: Understand that light is made up of different colors, each with a different wavelength.
Step 2: Recognize that red light has the longest wavelength compared to other colors like blue or green.
Step 3: Learn that in thin films, such as air between glass plates, light can interfere with itself, causing some colors to be more affected than others.
Step 4: Realize that colors with shorter wavelengths (like blue) are more affected by interference than colors with longer wavelengths (like red).
Step 5: Conclude that red light, having the longest wavelength, will be the least affected by interference in the thin film.
