| light waves are this type | transverse waves |
| sound waves are this type | longitudinal waves |
| convex | like the eye; when the mirror is close the image is distorted; when you move away the image gets smaller and not as distorted; stores use them to see a big area; slightly convex makes you look thinner |
| concave | inside the bowl shaped; when the mirror is close the image is large and distorted; move away and it is upside down; think fun house mirror |
| refraction | the bending of light as it moves from 1 medium to another |
| reflection | when light rays bounce off a surface the angle of incidence (the angle describing how it hit) = the angle of reflection |
| regular reflection | happens on a smooth surface and you see yourself |
| diffuse reflection | happens on a rough surface (bricks) and you see no reflection |
| the type of energy that forms light | electromagnetic |
| these objects make their own light | luminous objects |
| these have light shine on them and they reflect the light | illuminated objects |
| "living organisms" that create their own light source | bioluminescence |
| the absence of light | shadow |
| this travels in straight lines from its source | light |
| when light hits matter it soaks in | absorb |
| when light hits matter it bounces back | reflects |
| when light hits matter it goes through it | transmits |
| this material allows light to pass through it clearly; you can see it clearly | transparent |
| this material allows light to pass through but it is scattered; you might see an image but it is fuzzy/distorted | translucent |
| this material does not allow light to passs through it; light is blocked/absorbed; you can not see through it | opaque |
