LIGHT

LIGHT. Opaque, Translucent, Transparent. Opaque – only absorbs and reflects light Translucent – allows some light to pass through, some light absorbed and reflected Transparent – allows almost all the light to pass through, only a small amount of light absorbed and reflected. TRANSPARENT.

Presentation Transcript

  1. LIGHT

  2. Opaque, Translucent, Transparent • Opaque – only absorbs and reflects light • Translucent – allows some light to pass through, some light absorbed and reflected • Transparent – allows almost all the light to pass through, only a small amount of light absorbed and reflected

  3. TRANSPARENT OPAQUE TRANSLUCENT

  4. Law of Reflection • The angle at which a light wave strikes a surface is the same as the angle at which it is reflected.

  5. Regular vs. Diffuse Reflection

  6. Refraction • Caused by a change in the speed of light • If the light wave is traveling at an angle and the speed that light travels is different in the two materials  the wave will be bent (refracted)

  7. Normal Angle of Incidence Incident Ray Air Water Angle of Refraction Refracted Ray

  8. Prism

  9. Mirage • A result of the air above the ground being much warmer or cooler than the ground, causing refraction due to a change in the speed the light is traveling
