What causes a ray of white light to split into seven colors when passed through a prism? a. refraction b. reflection c. filtering d. absorption

Refraction causes the light to bend. Each wavelength bends by a slightly different amount.

The light doesn't "split into 7 colors". It smears, into all of the thousands of colors that eyes can detect, plus some that they can't.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
