Coloured Light Filters Science

The filters will either block absorb the laser light or allow it to be transmitted passed through.

Coloured light filters science.

For example an orange filter transmits orange light but absorbs all the other colours. Light from a torch or the sun is a good example of this.

White light is actually made of all of the colours of the rainbow because it contains all wavelengths and it is described as polychromatic light.

Finding the science in your world. Once you have figured out the rules of how various color filters interact with specific colors of light take your understanding a step futher by figuring out how color tinted sunglasses work. Lasers are extremely dangerous and can cause permanent eye damage. Launch interactive and start exploring.

When you marked with your blue or green colors however the ink absorbs the color red. In the case of the magenta dichroic filter illustrated below in. Coloured light there are three primary colours in light. No red light is absorbed by the filter so you can see those colors through the filter relatively unchanged.

Interference filters these filters differ from absorption filters in the fact that they reflect and destructively interfere with unwanted wavelengths as opposed to absorbing them. Colored lenses change our perception of the world s colors by acting like filters. Coloured filters are also used in theatres to create certain moods or settings. When white light passes through a coloured filter all colours are absorbed except for the colour of the filter.

For example blue filters may be used to create a night time scene while yellow filters may be used to create a sunny day scene. The term dichroic arises from the fact that the filter appears one color under illumination with transmitted light and another with reflected light. Light in these colours can be added together to make the secondary colours magenta cyan and yellow. Coloured filters are used in photography and sunglasses to filter out unwanted colours of light.

When you look at your paper through your red filter the paper looks red because the filter only lets red through. Red green and blue. For example glasses with blue lenses absorb green light and red light but allow blue light and blue containing colors such as purple to pass through into the eye. Color pigments paints dyes or inks show color by absorbing certain parts of the light spectrum and reflecting the parts that remain.

Color filters work the same way absorbing certain wavelengths of color and transmitting the other wavelengths.
