Passing a beam of white sunlight through a prism produces which of these?
AA single beam of violet
BA pair of dark shadows
CA ring of white light
DA band of all the colors
Answer & Solution
Correct answer: D. A band of all the colors
1. White sunlight is not a single color but a mixture.
2. A prism bends each wavelength by a slightly different amount and spreads them apart.
3. The result is a band showing all the colors of the rainbow, called a spectrum.
