Colours of Light 2

When red and blue lights are mixed on a screen, they produce​ ​ (a)  

• magenta
• cyan
• yellow

Match each term (Column A) to the correct definition (Column B).

• Absorbs some lights and transmits others

• Refraction

• Separation of white light into different

• Reflection

• Speed change and bending of light

• Dispersion

• Bouncing of light off a surface.

• Filter

Type question here including an Put the following steps in order to describe how a prism produces a spectrum of colors from white light.

• • White light disperses into its component colors as it refracts.

• 1. The separated colors exit the prism, producing the visible spectrum.

• • Each color bends slightly differently based on its wavelength.

• Light travels from air into the prism.
