1 If the electron behaved as a classical (non-quantum) particle and NOT somehow connected to a spring inside the metal, then one would expect that photoelectrons would be emitted _______

	above a threshold intensity
	above a threshold wavelength
	above a threshold frequency
	at a specific frequency

2 If the electron behaved as a classical (non-quantum) particle and the electron was somehow connected to a spring inside the metal, then one would expect that photoelectrons would be emitted _______

	above a threshold intensity
	above a threshold wavelength
	above a thresholdfrequency
	at a specific frequency

3 In the photoelectric effect, how was the maximum kinetic energy measured?

	by measuring the voltage required to prevent the electrons from passing between the two electrodes.
	by measuring the wavelength of the light
	by measuring the distance between the electrodes
