Click on the light beam on the right, move the filter slider, and make some observations about what you notice about the light, the filter, and what is perceived.

It seems like you're working with a simulation or an experiment related to light and color filters.

For your observations about the light and the filter:

  1. Observations: As you move the filter slider, you may notice that the intensity or color of the light changes depending on the type of filter you are using (such as red, green, or blue filters). The filtered light might become dimmer or take on a specific hue corresponding to the filter. You may also observe how certain colors of light are absorbed while others are transmitted; for instance, a red filter allows red light to pass through while blocking other colors.

  2. What the filter did to the light: The filter selectively allowed certain wavelengths of light to pass through while absorbing others. This effect results in the perceived color change of the light. For example, if a blue filter is used, the transmitted light appears blue, while other colors are diminished or completely blocked.

For Part 2:

  • When no lights are on, the perceived color is likely black or dark, as there is no light being emitted.
  • Upon clicking the Pause/Play button, you might observe that when you turn on the RGB bulbs, various combinations of red, green, and blue light will produce different perceived colors, depending on which bulbs are activated.
