What color is a green object in red light?
The light that is reflected is the colour of the object in that light….Coloured light.
| Appearance of object in white light | |
| White paper | White (no colours absorbed) |
| Red apple | Red (all colours absorbed except red) |
| Green apple | Green (all colours absorbed except green) |
Why green ball appears black in red light?
The observer sees the object as the colour green. In diagram 2, the same object is seen under red light. Because the green surface absorbs all colours other than green, no light at all is reflected from the object. No light enters the observers eye, so the object appears a black colour.
Why does red light passes through easily in red cellophane what happens to the green light?
Cellophane and coloured glass are also transparent because you can see through them. The cellophane absorbs other colours of light. For example, green light will not pass through red cellophane. The green light is absorbed by the red cellophane.
What is the effect of mixing red and green Colour?
If you mix red and green together, you will get a shade of brown. The reason for this is because red and green together include all of the primary colors, and when all three of the primary colors are combined, the resulting color is brown.
What does a green object look like under a red light?
A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can’t reflect other colours, so it looks black. Home
What makes an object red when white light falls on it?
When white light falls upon a green surface all of the components of the white light that are not green are absorbed by the surface while the green light is scattered. A red object is red when white light falls upon it because it absorbs all the components of white light with the exception of the red component which is scattered.
How is a yellow object different from a green object?
A yellow object is slightly different because yellow light can be made from mixing red and green light so the object is yellow because it is scattering red and green light and absorbing all of the other colours. What do you think if we illuminated a green jersey with red light?
How does the colour of an object depend on its wavelength?
e.g., a black object scatters little light, and absorbs light at all visual wavelengths; a green object scatters more green light than other colours, which it absorbs more. It has already been mentioned that the colour of light is dependant on its wavelength with red light having a longer wavelength than blue light.
