Light and the Electromagnetic Spectrum

Light and the Electromagnetic Spectrum

1. We see things when light travels from as source and is reflected by an object

   • The light transfers energy from the source to our eyes
     • Light is a type of electromagnetic wave

2. Our eyes can detect certain frequencies of light

   • We refer to these frequencies as visible light
     • Different frequencies cause us to see different colours
       • Lower frequencies of visible light appear more red and higher frequencies appear more blue
