All other colours of light shining on the red flower are __________.
All other colours of light shining on the red flower are __________.
How to approach this question
If the flower reflects red light to appear red, what must happen to all the other colours (orange, yellow, green, blue, violet) that are also part of the sunlight hitting it?
Full Answer
absorbed
The colour of an opaque object is determined by which wavelengths of light it reflects. Sunlight is white light, which is a mixture of all colours of the visible spectrum. When white light shines on a red flower, the surface of the flower absorbs all colours *except* red. The red light is reflected off the surface. When this reflected red light enters our eyes, we see the flower as red.
Common mistakes
✗ Choosing "reflected". If all colours were reflected, the flower would appear white.\n✗ Choosing "refracted". Refraction is the bending of light as it passes through a medium, not what determines the colour of an opaque object.
