  1. Let the light shine • Sources of Light • Luminous • Produces light • Incandescent • Light due to high temperatures • Electromagnetic Spectrum • A range of electromagnetic radiation ranging from very short wavelengths to very long wavelengths Long waves Short waves Low energy High energy Radio Visible X-rays

  2. Let the light shine • Remember this from the well know Physicist: Roy G. Biv • Colors of the spectrum • Red • Orange • Yellow • Green • Blue • Indigo • Violet • Red = Short word = Long wave • Violet = Long word = Short wave

  3. Let the light shine • Path of light • Always in a straight line • Why can we see when in the shade of a tree ???? • Transparent • Light passes through • Opaque • Reflects & absorbs light • Translucent • Light can pass through • Speed of Light • 186,000 mi./sec.

  4. Let the light shine • Reflection & Refraction: Which is which • Law of Reflection & Refraction • Angle of incidence is equal to the angle of . . . . • Reflection • We see something because light “bounces” reflects off of the object • Reflecting surfaces • Concave (in) • Convex (out) • First surface mirror

  5. Let the light shine • Refraction • Light passing through but is bent as it passes through the medium • Refraction is due to a change in the velocity of light • Chromatic aberration

  6. Let the light shine • A System of Lenses • Camera and The Eye • The Rainbow • Conditions • A process of refraction & reflection • Greenhouse Effect
