What color will a green apple appear to be when viwed through a red filter?
red apples
What color does red litmus turn into in apple juice?
Apple juice is slightly acidic and therefore red litmus will not change color.
What color band does a red apple absorb?
A red apple absorbs mainly red and blue wavelengths of light, while reflecting green and yellow wavelengths. This absorption and reflection process gives the apple its characteristic red color.
What color does red filter absorb?
A red filter absorbs green and blue light, allowing only red light to pass through.
What is a color of light that passes through the filter?
The color of light that passes through a filter depends on the properties of the filter. If the filter is red, only red light will pass through. If the filter is blue, only blue light will pass through, and so on.
What happens when you look at a blue object through a red filter?
When you look at a blue object through a red filter, the object will appear darker and possibly black because the red filter blocks out most of the blue light. The red filter only allows red light to pass through, which results in absorbed blue light and altered color perception.
What color will the green apple appear to be when viewed through a red filter?
Black, or nearly so. The apple reflects only green light, the red filter only lets red light through, so nothing reaches the eye.
Why wouldn't you see any colour if you put a blue filter in front of a red filter?
If you put a blue filter in front of a red filter, the blue filter would block all the red light and only allow blue light to pass through. The red filter would then block all the blue light that passed through the blue filter. This would result in no light passing through the filters, so you wouldn't see any color.
What are the differences between red and blue 3D technology?
Red and blue 3D technology, also known as anaglyph 3D, use different color filters to create the illusion of depth. Red 3D uses a red filter for the left eye and cyan filter for the right eye, while blue 3D uses a blue filter for the left eye and red filter for the right eye. This results in slightly different color perception and can affect the overall viewing experience.
What color would white light appear viewed through red filter and pure blue?
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.
What colour is red light if you look at it through a blue filter?
You can't see it because a blue filter only lets blue light in, and red is made up of just red light, no blue, so none passes through (or it gets reflected, can't remember which)
What would happen if you shone a bright red light on a green apple?
Since the apple is green, it would absorb any light that is not the same color as the apple. In this instance, the apple would appear very dark or even black since there is no green in the red light you are shining on the apple. A popular science experiment involves a shoe box, a piece of colored plastic or glass, a few objects (such as the apple), and a flashlight. If a red apple is being used with a red filter, the apple would appear to be a bright red since the apple is also red. The red filter allows the red color being reflected off the apple to pass through. Switch the filter to a green one, and the apple appears black since the filter effectively filters out all colors except green.
