NOTES

• Check point 1• Which color of visible light has the longest wavelengths?• Red and orange have the longest wavelength.• Checkpoint 2• Why would particles from volcanic eruptions make sunsets

and sunrise more red?• Its more red cause the energy from the sun absorbs the

ultraviolet radiation.• List three forms of radiation from the sun. How are these

alike? How are they different.• What happens to the energy from the sun that is absorbed

by the Earths surface?• Why is the sky blue? Why are sunsets often red?• What might conditions on earth be like with the green

house effect?

Term That You'll See Often

• Electromagnetic waves

• Radiation

• Infrared Radiation

• Ultraviolet Radiation

• Scattering

• Green House Effect

Vocabulary

• Electromagnetic waves-A form of energy that can travel though space.

• Ration-The direct transfer of energy through empty space by electromagnetic waves.

• Infrared radiation-a form of energy with wave lengths that are longer then visible light.

• Ultraviolet Rations-A form of energy with wavelengths that are shorter then visible light.

• Scattering-reflection of light in all directions.• Green House Effect-The process by which heats trapped in the

atmosphere by water vapor, carbon dioxide, methane, and other gases that form a “blanket’’ around the earth.

Electromagnetic WavesWhat is it?

Electromagnetic waves are made when an electric field and a magnetic field send out waves of energy that overlap. Electromagnetic waves exist in a wide range of frequencies and wavelengths and can travel through all media. when they are absorbed, electromagnetic waves produce heat.

Give me an example!

Electromagnetic waves power an amazing number of things we use every day. Radio waves enable us to transmit and receive sound over great distances. X-rays let us see inside people's bodies to check for broken bones. Microwaves help us warm up food in a hurry and transmit television signals using satellites. Even the sun itself transmits electromagnetic waves in the form of ultraviolet radiation. Copyright ©2005, PCS Edventures, Inc.All Rights Reserved.
