Correct Answer:
A. Spectrum
Explanation:
A spectrum is created when white light passes through a prism because the various wavelengths of light travel at different speeds within the glass. This causes each color to refract, or bend, at a unique angle, resulting in the separation of the white light into its constituent colors: red, orange, yellow, green, blue, indigo, and violet. This phenomenon is known as dispersion.
