Electromagnetic Energy being transferred by the Sun
Red = Long Wavelength, Low Frequency, & Low Energy Violet = Short Wavelength, High Frequency, & High Enegy
Some waves travel through objects and some are bounced off (reflected) or absorbed
A PRISM will separate light into its different colours due to the different speeds of each colour. Violet is the fastest so it will slow down the most
If the eye only has sensory cones for the PRIMARY COLOURS RED, GREEN, & BLUE how do we see other colours? Secondary Colours are a mix of: Yellow = R + G Cyan = B + G Magenta = R + B White light = R + B + G ( all light reflected) Black = all light absorbed
What weather conditions are needed to make a rainbow? (hint you need a light source and prism) What other objects (or situations) have you seen that will separate white light into its spectrum colours (ie. Rainbow)?
What do you notice? What uses Infrared radiation? What is UV protection on Sunscreen? What type of radiation has the longest wavelength and lowest enegy? What type of radiation has the shortest wavelength and the highest energy? What types of radiation have higher energy than visible light? Which have lower energy than visible light?
