Properties of light

Properties of Light

  • When light strikes an object it is:


Properties of light1

Properties of Light

  • When light strikes an object it is:

    • Reflected


Properties of light2

Properties of Light

  • When light strikes an object it is:

    • Reflected

    • Transmitted


Properties of light3

Properties of Light

  • When light strikes an object it is:

    • Reflected

    • Transmitted

    • Absorbed


Properties of light4

Properties of Light

  • What happens to the light depends on the material


Properties of light5

Properties of Light

  • What happens to the light depends on the material

    • Transparent (clear) materials- transmit light


Properties of light6

Properties of Light

  • What happens to the light depends on the material

    • Transparent (clear) materials- transmits light

    • Translucent (see through) materials- scatters the transmitted light


Properties of light7

Properties of Light

  • 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


Properties of light8

Properties of Light

  • Color of objects is the color it reflects

    • Ex- an orange is orange because it absorbs every color BUT orange, instead it reflects orange


Properties of light9

Properties of Light

  • 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


Properties of light10

Properties of Light

  • 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


Properties of light11

Properties of Light

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


Properties of light12

Properties of Light

  • 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


Properties of light13

Properties of Light

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


Properties of light14

Properties of Light

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

  • Lens- curved glass or transparent material that refractslight


Properties of light15

Properties of Light

  • 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)


Properties of light16

Properties of Light

  • Convex lens- thicker in the center than the edges (bends light in)

  • Concave lens- thinner in the center than the edges (bends light out)
