Name and define one of the behaviors of electromagnetic waves

Behaviors of LightTRANSMIT

Light passes through an object

ABSORBLight is absorbed or soaked up by an object

REFRACTThe path of a light wave changes directions as it hits light

REFLECTLight bounces back as it strikes an object

This is how we see colors!!!!

The Electromagnetic Spectrum

The electromagnetic spectrum are the colored waves that make up visible light

Energy of Waves

TIME

• Frequency: the number of waves that occur over a period of time

• The GREATER the FREQUENCY of a wave the HIGHER ENERGY

Energy of Waves

Light in the Ocean

Light in the OceanRemember the way we see color!

Light waves REFLECT off an object creating the image of color

To see a color the light waves responsible must be present to reflect off an object

Lower frequency, lower energy light waves are absorbed first

Red, orange, and yellow only reach shallow depths

Higher frequency, higher energy light waves can travel to greater depths

In the deep ocean only blue, indigo, and violet light waves remain
