What color is a green object if red light strikes it?
The green object will appear black because red light is absorbed by green objects.
Is true when light strikes a green leaf most of the green part of the spectrum is reflected?
Yes, it is true that when light strikes a green leaf, most of the green part of the spectrum is reflected. This is because chlorophyll, the pigment responsible for photosynthesis in plants, absorbs light primarily in the blue and red wavelengths, while reflecting green light. As a result, leaves appear green to our eyes. This reflection of green light is a key characteristic of healthy green foliage.
When light strikes a green leaf how does this explain why leaves appear green?
Light that is white contains all the colours. When the light hits the leaf, it absorbs all the colours apart from the green light which is reflected back out to your eyes. So you see the leaf as green.
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)
Describe what happens when light strikes a green leaf?
When light strikes a green leaf, the leaf absorbs red and blue wavelengths of light while reflecting green wavelengths. The absorbed light is used in the process of photosynthesis to convert carbon dioxide and water into glucose and oxygen, which the plant uses for energy and growth. The green pigment chlorophyll in the leaf is responsible for absorbing the light and carrying out photosynthesis.
What color would a cucumber appear in green light white light and red light?
Green light - Green, White light - Green, Red light - Black
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.
When a white lite strikes a green object only the green component is absorbed?
A green object appears green because it reflects green light and absorbs all other colors present in white light. When white light strikes the object, the green component is absorbed and the rest is reflected back to our eyes, creating the perception of green color.
What happens when a white light strikes a red apple?
The red apple absorbs most of the colors in the white light spectrum, except for red. The red color is reflected off the surface of the apple, which is what we perceive with our eyes. This is why the apple appears red when white light strikes it.
Which light makes when magenta light into green light?
A red light will be needed to combine with magenta light to produce green light. Green light is the complementary color to magenta, so by mixing red light with magenta light, the result will be green light.
What happens to white light when it strikes a red shirt?
When white light strikes a red shirt, the shirt absorbs most of the colors in the light spectrum except for red. The red color is reflected off the shirt's surface, which our eyes perceive. This is why the shirt appears red to us.
What colour is produced by mixing red and green light?
It is yellow-- mixing red and green PAINT produces brown; mixing red and green LIGHT produces yellow.
