Which statement about visible light is false?

• A. Visible light is part of the electromagnetic spectrum.
• B. Visible light includes colors from red to violet.
• C. Visible light cannot be refracted by a prism.
• D. Visible light can be bent by refraction.

Answer: (C)

Visible light is part of the electromagnetic spectrum and includes colors from red to violet, traveling through air and other media. When light enters a different material, its speed changes. This change in speed makes the light bend, a process called refraction. A prism uses this effect and disperses the different colors because each color bends by a different amount. So the statement that visible light cannot be refracted by a prism is false. The other points are true: visible light is part of the electromagnetic spectrum, and it can be bent by refraction.
