Question

When the filter is the same color as the light source, what did you observe in the simulation?

Answer 1

When the filter is the same color as the light source, the observed effect in a simulation typically demonstrates that the light passing through the filter will remain unchanged in color. This is because the filter allows only the same wavelength (color) of light to pass through while absorbing other wavelengths. As a result, if you were to shine a colored light source—such as red light—through a red filter, the light that emerges would still be red. Conversely, if a different color of light were used, such as green or blue, the red filter would absorb those wavelengths, resulting in little to no light reaching the observer, appearing as dark or black. This illustrates the principles of color filters and the relationships between light wavelengths and color perception.
