When light passes through a translucent green curtain, several things can happen to the wavelength of the light, depending on the properties of the curtain and the specific wavelengths involved.
Absorption: The curtain may selectively absorb certain wavelengths of light. If the curtain is designed to appear green, it likely absorbs light in other parts of the spectrum while allowing green light to pass through. The absorbed wavelengths are typically converted into heat energy within the curtain.
Transmission: The curtain may allow certain wavelengths of light to transmit through it. In the case of a green curtain, it would allow green light to pass through while partially blocking or scattering light in other parts of the spectrum. The transmitted light maintains its original wavelength unless affected by other factors.
Scattering: When light encounters small particles or irregularities in the material of the curtain, it can scatter in various directions. This scattering can result in a diffusion of the light, reducing its intensity and potentially altering its perceived color.
Reflection: Some light may reflect off the surface of the curtain, depending on its properties. The reflected light would generally retain its original wavelength unless affected by factors such as interference or polarization.
It's important to note that the specific behavior of light passing through a translucent green curtain depends on the composition, thickness, and characteristics of the curtain material, as well as the properties of the incident light. Different materials and lighting conditions can result in variations in the interaction between light and the curtain, leading to different effects on the wavelength and overall appearance of the transmitted light.
