In the diagram, light is being passed through a glass prisim. Determine which of the following statements BEST descibes this process.

• 1-Ultraviolet light enters the prism 2- Light is refracted as it passes through the prism 3-and light separates

• 1- White light enters the prism 2-Light is refracted 3- Light separates

• 1-White light enters the prism 2- Light refracts through the glass 3- Wavelengths slow and speed stays the same

• 1-Infrared light enters the prism 2- Reflects through the prism and 3- Light separates
