Grade 7 Radiation Notes and Eureka Video

Radiation

·        Radiant energy is the transfer of energy by invisible waves given off by the energy source
·        These invisible waves are called infrared waves (a type of electromagnetic wave from the sun)
·        Infrared waves are given off by all heat sources, including you
·        Heat is radiant energy from the sun that reaches your skin
·        Radiant energy warms up objects when the waves of radiant energy come into contact with matter making the particles vibrate faster
