Why does a red tomato appear to be red under a red filter?

A red tomato appears red under a red filter because the filter selectively transmits red light while absorbing other colors. The red pigment in the tomato reflects or transmits the red light that passes through the filter, making it appear red to our eyes.


What colours of white light are absorbed by a red filter?

A red filter absorbs most of the colors of white light except red, which is transmitted through the filter. This means that the red filter reflects or transmits red light while absorbing other colors.


What colours of light will a blue filter absorbs and transnit?

A blue filter absorbs most colors of light except blue, which it transmits. This means that it will absorb red, green, and other colors of light, while allowing blue light to pass through.


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

After pure, white light passes through a red filter, all the other colors in the spectrum will flow out of the other side. My mistake, I had a faulty source. A red light filter will cause the image to appear as different shades of red. Since it is a red filter only red light can pass through. So you finish up with red light. Whether it is focussed to an image or not is of no consequence. As to different shades of red, you will get the shade of red that is passed by the filter.


What happens if light passes through a filter?

When light passes through a filter, certain wavelengths are allowed to pass through while others are absorbed or blocked. The filter selectively transmits certain colors or polarizations of light, resulting in the filter altering the properties of the transmitted light.

What does red light look like under a magenta filter?

When red light passes through a magenta filter, it appears darker or may even be absorbed completely. A magenta filter primarily transmits blue and red light while absorbing green wavelengths. Since red light is already on the red side of the spectrum, it may not be transmitted effectively, leading to a muted or absent appearance. Thus, the red light's intensity diminishes significantly under a magenta filter.


Does red light transmit red lighe waves?

No. But a " Red Shift" transmits Red Light....


If you look through a red filter at a sheet of green paper that is in white light what will you see?

The paper appears black. -- The paper is called "green" because it absorbs any light that isn't green, and reflects only green light to the observer. -- The filter is called "red" because it absorbs any light that isn't red, and transmits only red light through to the other side. -- There's no red light shining from the paper into the filter, so there's no light leaving the filter. The paper appears black.

What color or colors of light are transmitted by a piece of yellow glass?

Red and green light. Yellow glass transmits yellow light. Yellow light is a combination of red and green light. Therefore yellow glass transmits red and green light and absorbs blue light.


Does red glass only reflect and transmit red light waves?

No, red glass does not only reflect and transmit red light waves. It actually transmits the white light waves through the red glass creating a red glow. A transparent object generally transmits light while a solid object reflects light.


What does green filter do to white light?

A green filter selectively transmits green light while absorbing other wavelengths. When white light passes through a green filter, it removes the red, blue, and other colors, resulting in light that appears green. This process allows only the green portion of the spectrum to pass through, creating the effect of colored light.
