Understanding the Interaction of Light with Objects

When light strikes an object, it can be reflected, transmitted, or absorbed, depending on the material of the object. Transparent materials allow light to pass through, translucent materials scatter light, and opaque materials absorb and reflect light. The color of objects is the color they reflect, not the color they absorb. For example, an orange object appears orange because it reflects orange light, while absorbing other colors.

Presentation Transcript

1. When light strikes an object it is:

2. When light strikes an object it is: 1) Reflected

3. When light strikes an object it is: 1) Reflected 2) Transmitted

4. When light strikes an object it is: 1) Reflected 2) Transmitted 3) Absorbed

5. What happens to the light depends on the material

6. What happens to the light depends on the material Transparent (clear) materials- transmit light

7. What happens to the light depends on the material Transparent (clear) materials- transmits light Translucent (see through) materials- scatters the transmitted light

8. What happens to the light depends on the material Transparent (clear) materials- transmit light Translucent (see through) materials- scatters the transmitted light Opaque (not see through) materials- absorbs and reflects

9. Color of objects is the color it reflects Ex- an orange is orange because it absorbs every color BUT orange, instead it reflects orange

10. Color of objects is the color it reflects Ex- an orange is orange because it absorbs every color BUT orange, instead it reflects orange If you do not shine orange light on it, it will appear black

11. Color of objects is the color it reflects Ex- an orange is orange because it absorbs every color BUT orange, instead it reflects orange If you do not shine orange light on it, it will appear black Black is the absence of color, white is the blending of all colors

12. Reflection- when an object or wave bounces back off a surface

13. Reflection- when an object or wave bounces back off a surface Law of reflection- angle made from incoming wave = the angle made from reflected wave

14. Refraction- bending of light waves due to a change in speed

15. Refraction- bending of light waves due to a change in speed Lens- curved glass or transparent material that refracts light

16. Refraction- bending of light waves due to a change in speed Lens- curved glass or transparent material that refracts light Convex lens- thicker in the center than the edges (bends light in)

17. Convex lens- thicker in the center than the edges (bends light in) Concave lens- thinner in the center than the edges (bends light out)
