An emitter of blue light shining on/through a red filter.
The red filter appears red because it block all light except red. So trying to shine blue through it should attenuate the blue heavily. Only red can pass through the red filter easily.

What would happen if you put blue filter in the ray of light?

If you put a blue filter in the path of a ray of light, the filter would absorb all colors of light except for blue. This would result in the light passing through the filter appearing blue in color.


What geometri term best describes the light that shines from a flashlight?

A "beam" or "ray" of light would best describe the light that shines from a flashlight.


What would happen if a light with a red filter was shined through a blue filter?

If a red light is shined through a blue filter, the blue filter would absorb the red light since it is not in the transmitted light spectrum. This would result in very little to no light passing through the blue filter, creating darkness or a very dim output depending on the intensity of the red light source.


What would happen if you put a blue filter inthe ray of light coming from the red filter?

If you place a blue filter in the path of light coming through a red filter, the blue filter will absorb or block the red light, potentially resulting in less intense light or a different color of light that is transmitted through. The combination of the two filters will likely produce a color that is a mix of the two original colors, such as purple or magenta.


What color would white light appear viewed through filter?

It depends on what kind of filter, e.g. a blue filter absorbs everything except blue light, so only blue light comes out, which is why the filter looks blue, and is referred to as a "blue filter".

What would happen if you looked at a red light with a red filter?

A red filter blocks every color except red from getting through, so you would see red.


What colour would a grean object be if a red light shines on it?

black


A beam of white light shines through a glass prism in a darkened room to produce the colors of white light How would the pattern on the screen change if a pure red filter were placed in the path?

If a pure red filter is placed in the path of the white light, only the red component of the light would pass through, resulting in a pattern on the screen showing only shades of red. The other colors of the spectrum that were originally present would be blocked by the filter.


How would you know that a flashlight is working?

If it has light, the flashlight is working.

If red light shines on a red flower what color would the flower be?

Obviously the excact same Red.


If white light were shone through a green filter which light would pass through the filter?

Only the green portion of the white light would pass through the green filter. The filter absorbs all colors except green, allowing only green light to pass through.


What would happen if a blue filter was used for spectroscopy?

Using a blue filter for spectroscopy would selectively transmit blue wavelengths of light while blocking other wavelengths. This would result in the spectrograph only detecting and recording blue light emitted or absorbed by the sample being analyzed, leading to a limited spectral range in the data collected.
