The Study of Light Quiz - 24

What does a prism do?

• combines the many colors of visible light into white light by bending each wavelength at a different angle

• separates sunlight into ultraviolet and infrared radiation

• separates visible light into its many colors by bendingeach wavelength at a different angle

• changes the wavelength of electromagnetic radiation thatpasses through it

• red

• green

• violet

• indigo
