Drill: Refraction and Lenses

 What is Snell's Law - the bending of a wavefront as its moves from one medium to a second

 What is the formula to calculate the critical angle -- when is it used?

 What is the formula that relates do, di, and f for a thin lens?

 When is di positive? negative?

 When is f positive? negative?

 What formula can be used to calculate the magnification for a thin lens?

 What formula is sued to to calculate the power of a lens?

 Which type of image can be projected onto a screen?

 Describe the three rays used to graphically locate the image for a converging lens.

 What types of rays form a virtual image?

 formula to calculate the power of a series of thin lenses in close combination (with no medium between them)

 What is the only situation when a converging lens forms a virtual image? is the image upright or inverted? enlarged or reduced?

 What type of image is ALWAYS formed by a diverging lens? Is it upright or inverted? enlarged or reduced?

 True or false. Changing the medium that surrounds a lens can change it from a converging lens to a diverging lens?

 What is the formula to adjust the wavelength of light in a transparent medium

 What is the thin lens equation for converging lens

 What is the thin lens equation for diverging lens
