What colour would a white object be if a blue light shone on it?
blue
What kind of pattern of light would you get if you shone monochromatic light on a diffraction grating?
If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.
If a red light is shone on a green object what would the colour be?
black
What color would a red object appear to be if you shone a green light on it?
it would appear black.
What colour will a green object be if only blue light was shone on it?
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
What would a green object look like shone onto a yellow light?
black
What color would a red object appear to be if you shone only green light on it?
it would appear black.
If you shine a blue light on a blue object what color will the object turn?
The object will appear to be blue. However, the object would be indistinguishable from an object that reflects all colors of light. If yellow light were shone on an object that reflects only blue wavelengths, the object would appear to be black.
If white light were shone through a green filter which light would pass through the filter?
Mostly green.
What colour would a yellow object be if only a blue light was shone on it?
Purple, Cuz aliens dont exist
What colour will a white object appear if only red light was shone on it?
Red. The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.
What happens when red light is shone onto a wall?
Any object that has light shone on it would appear in a particular color because the said object absorbs all the other colors of the spectrum and reflects one single color. when the light itself consists of a single color, the color of the object gets modified because the reflected light contains the color of the light and then part that is reflected. For ex, the wall in the question would appear red if the light is only one wavelength but would appear as a combination of red and its own natural color if the light is a combination of different wavelengths.
