(blank) variable should be negative for all inverted images for both mirrors and lenses
What is hi (image height)?
200
Young's observations from the 'two slit' light experiment.
What is an interference wave pattern?

minimum frequency required to emit any electrons from the metal surface
What is threshold frequency?

300
light consisting of a single frequency (or wavelength)
