What happens when white light strikes a red opaque object. What about blue light. red light. violet light?
When white light strikes a red object, the object would appear red. The object would have reflected the red light within the white light while all other colours would have been absorbed. When blue light strikes a red object, it would appear black as there is no red light in blue light as it is a primary colour. As a result, the blue light would be completely absorbed by the red object. So no light would be reflected from the object. When violet light strikes a red object, it would appear red, as violet is a combination of blue and red light. The blue light would be absorbed while the red light would be reflected. It is good to learn and revise the light spectrum and primary and secondary light colours. Primary light colours are: Red, Green and Blue Secondary light colours are: Yellow, Cyan and Violet The combinations are: Red + Green = Yellow Green + Blue = Cyan Blue + Red = Violet (or Magenta depending on how you have been taught)

A painted wall appears yellow?
The paint absorbs blue light, which means red and green light are preferentially reflected and red and green combined appear yellow.This may be the reverse of what you learned in art class; the reason is that mixing pigmentsinvolves subtractiveprimary colors and mixing light involves additivecolors. Shine a red and a green light on the same spot and it will appear yellow.

What colour would red green and white appear if a green light was shone at them?
While the ball would still be green it will appear black. Anything green absorbed all colours except green. The green light is reflected to your eyes which makes it look green. Thus in red light (with no green in it) the red will be absorbed and no green light can be reflected to your eyes so the ball will look black.

Why will the leaves of a red rose be warmed more than the petals when illuminated with red light?
The reason the rose is red is because it reflects red light. So if shining a red light on a red rose, most of the light will be reflected by the rose, but absorbed by the leaves. Absorbing light warms an item.
What color does a green leaf appear to be in red light and why?
It appears black. A green pigment can only reflect green light and red light is a primary colour, that is it contains only red.
