Answer
Dispersion is the phenomenon whereby white light breaks up (spreads out) into its component colors. It occurs when light passes through a medium, such as a prism, causing the different wavelengths to refract at different angles.
Step 2
Identifiseer die kleur wat deur nommer 3 en 6 verteenwoordig word. Skryf die korrekte kleur langs die nommers in jou ANTWOORDEBOOK neer.

Answer
The dispersion is responsible for the different wavelengths of visible light ranging approximately from 400 nm (violet) to 700 nm (red).

Answer
Electromagnetic waves can propagate in a vacuum.
They transfer energy and have both particle (photon) and wave properties.
