theres no such thing as color??

Question

is that true?

in science my teacher
was saying there is no such thing as color
cus the only reason you see color is cus of the light

for example
if the shirt was green it would seem green in the light
but in the dark its no color
so if there was no light
there wont be color

is that true?

Answer 1

Different colors of light have different wavelengths. That's the only thing that separates two colors - what wavelength they have. Light that we can see with our eyes have wavelengths from 300nm (violet) to 700nm (red). There is plenty of light out there at greater or smaller wavelengths that we can't see (the whole electromagnetic spectrum) because our eyes are not sensitive to it, like infra red and ultraviolet.

Answer 2

No that's not true. Color is the physical property that defines which wavelengths of light an object reflects or emits. Just because you turn the light off doesn't mean your blue shirt ceases to be blue.

That's a pointless thought experiment. That's like asking if a tree falls in the middle of the woods and no one is around, does it make a sound? Of course it does!

Answer 3

Yes the colors are our eye's response to the different wavelengths of visible light. Because the wavelengths travel through glass at different speeds, a prism spreads out the white light from the sun so we can see the bands of color from red to violet. If there is not enough light energy, the cells in the retina of our eyes do not register color but they still register enough to see the object.

Answer 4

Equip yourself to respectfully argue this with your teacher. Understand the concepts and arm yourself with suitable definitions and references for them. Then, ask your teacher to define color. Offer definitions more suited to your point of view, and explain the differences. Your teacher is quibbling over terminology, hopefully for the purpose of getting you to think, do research, and articulate your point of view. That's an extremely valuable skill, woefully lacking in modern society.

Answer 5

No!
The light does reflect a color but not always.

Answer 6

i guess so
