Review for 8th Science FCAT (Light and Waves)

White light can be separated into colors what is the correct order from the longests to shortest wavelengths

• Red, Orange,  Yellow, Indigo,  Blue, Green, Violet (ROYIBGV)
• Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROYGBIV)
• Red,Orange, Blue, Yellow, Indigo, Green (ROBYIG)
• Orange, Blue, Red, Yellow, Indigo, Green (OBRYIG)

when white light strikes a green wall, all of the visible wavelengths ?

• are absorbed
• are absorbed except for the green wavelength, which bounce off the wall
• Bounces off the wall
• Bounce off of the wall except the green wavelength, which is absorbed
