In a Converging Mirror/Lens, is f positive or negative? | Positive |
What kind of mirror is a concave mirror? | Converging Mirror |
What kind of lens is a convex lens? | Converging Lens |
In a Diverging Mirror/Lens, is f positive or negative? | Negative |
What kind of mirror is a convex mirror? | Diverging Mirror |
What kind of lens is concave lens? | Diverging Lens |
Is i positive or negative in a real (inverted) image? | Positive |
What kind of lens gives a real (inverted) image? | Converging usually does unless 0 < f, then you get a virtual (upright) image. |
Is i positive or negative in a virtual (upright) image? | Negative |
What kind of lens gives a virtual (upright) image? | Diverging |
What is the speed of light in a vacuum? | 3.0 x 10^8 m/s |
Photon Energy Equation | E = hf = hc/wavelength |
Law of Reflection Equation | Theta 1 = Theta i |
Index of Reflection Equation | n = c/v , n >= 1 |
Law of Refraction (Snell's Law) | n1sin theta 1 = n2sing theta 2 |
Total Internal Reflection | n1 > n2 and Theta 1 > Theta critical, sin theta critical = n2/n1 |
Mirror/Lens Equation | 1/o + 1/i = 1/f |
Magnification Equation | m = -i/o |
Lens Power Equation | P = 1/f (Diopters) |
