| A | B |
|---|
| Ice crystals | Produce sundogs and haloes as light passes through them |
| Spherical Raindrops | Produce optical phenomena as rainbows and coronas |
| The Amount of refraction | determined by Snell's Law |
| Diffracted Light | Produce most of atmospheric optical illusions |
| Lapse Rate | temperature structure of the atmosphere |
| Acerage Temperature Profile in the Troposphere | 6.5 Degrees Celcius |
| bending light depends on | a specific lapse rate |
| desert regions atmosphere | is usually thin |
| density increases with height | for all lapse rates greater than autoconvestive lapse rate |
| Looming is pronounced | with strong surface inversions |
| towering | objects may appear much larger |
| foreshortening | objects may appear to be shorter |
| Sinking | objects may appear to be longer and flatter |
| Mirage | reflection of the sky on the ground from heat waves |
| green flash | distinct color appearing at sun- rise, and set. |
| Inversion | Negative Lapse Rate |
| Autoconvective Lapse Rate | 34.2degrees celcius/ km |
| Average temp profile | 6.5degrees celcius/km |
| Desert Mirage | a result of strong bending of light away from the ground |
| Highway Mirage | heated Highway appears to be covered in water |
