Light and the Electromagnetic Spectrum
Light as a Wave light is a visible form of energy most of the energy that surrounds us is invisible this energy travels in waves made of electric and magnetic fields called Electromagnetic Radiation
Light as a Wave Electromagnetic Spectrum = the entire range of visible and invisible energy waves
Properties of Waves wavelength amplitude
Wavelengths of the Electro-Magnetic Spectrum
Wavelength and Colour
How Light is Transmitted
Transparent: allows light to pass through Translucent: allows some light to pass through Opaque: allows no light to pass through
Light Reflection The reason we see objects is because they reflect light
Reflection in a Plane Mirror
Activity 4.11 How Light Reflects
Law of Reflection: When light reflects off a surface, the angle of incidence is always equal to the angle of reflection i = r
Looking in a mirror
Object distance vs. Image Distance
