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 d
_{o}
, d
_{i}
, and f for a thin lens?
When is d
_{i}
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
