What happens to light when it passes through a green filter?

When light passes through a green filter, it allows only green light to pass through while absorbing other colors. This is because a green filter is specifically designed to transmit green wavelengths of light and block all other colors. When white light, which contains all the colors of the spectrum, encounters a green filter, the wavelengths corresponding to green light are transmitted, while the red and blue components are absorbed.

As a result, the light that emerges from the filter appears green, as that is the only color that has been allowed to pass through. This property of filters is essential in various applications, including photography, stage lighting, and scientific experiments, where specific colors need to be isolated for analysis or creative effect.
