phyx eqns Wave/Optic

QuestionAnswer
Wave Speed v= λ f
Index of Refraction n = c/v
Law of Refraction n1 sin θ1 = n2 sin θ2
Critical Angle sin θ c = n2/ n1
Focal Length f = r/2
Lens and Mirror Equation 1/f = 1/di + 1/do
Magnification Equation M = hi/ ho or M= - di/do
Power of a Lens P = 1/f
Constructive Interference for a Double Slits and Diffraction Gratings d sin θ = mλ m = 1, 2, 3... d= separation of the slits
Destructive Interference for a Double Slits and Diffraction Gratings d sin θ = (m + 1/2) λ m = 1, 2, ,3..
Wavelength in a double slit experiment λ = dx/ mL d= separation of the slits x= position of the fringe at m m= integer ( fringe order) L = Distance from slit to screen
Minimum for a single slit D sin θ = mλ m = 1, 2, 3... D= width of the slit
Maximum for a single slit The largest maximum occurs at m =0 the others occur at the halves
Thin Films rule of Phase Change The light is reflected by a material whose index of refraction is greater than that of the material in which it is traveling the light will change phase by 1/2λ
Thin Film of air 2t = mλ m= 1... or 1/2... Depends on where the phase change happens. If the phase change happens to the inner reflected it in on whole numbers. If the phase change happens of the outer layer they will get constructive interference on half number λ
Thin Film` 2t = mλ/n m= 1... or 1/2... n= index of refraction
Polarizing Angle or Brewster's angle tan θ = n2/ n1

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
