Observations about the perceived light:
When you click and drag the slider below the filter color spectrum, you can notice that the color of the perceived light changes as you adjust the filter. Depending on the slider's position, the light may shift from one color to another across the spectrum, illustrating how different wavelengths of light are filtered out.
What the filter does:
The filter functions by allowing certain wavelengths (or colors) of light to pass through while blocking others. As you change the position of the slider, the filter selectively permits certain colors to come through, altering the overall appearance of the light that you see.
Observations with the white light bulb:
When you click on the white light bulb and move the filter color slider, you may observe that the light's color changes according to the position of the filter. For instance, if you set the filter to a particular color, you might notice that the white light appears to take on a tint of that color instead of staying white.
Why this happens:
This occurs because white light is composed of multiple wavelengths, and when you apply a colored filter, it only allows the wavelengths corresponding to that color to pass through while absorbing or blocking the others. As a result, the white light appears tinted due to the interaction with the filter.
Observations with the light beam on the right:
When you click on the light beam on the right and move the filter slider, you may notice that the light beam changes color similarly to the white light bulb. Depending on the filter color selected, certain colors may become more pronounced, while others become less visible. This could demonstrate how the filter response may vary based on the initial color of the light beam.
What the filter did to the light:
The filter altered the light by selectively filtering out specific wavelengths and allowing only certain colors to pass through. This change in the spectrum of visible light results in the perception of a different color, demonstrating the effect of the color filter on the light beam.
