Prediction Questions

Question 1: What will be the frequency of light emitted by a diode that turns on at 2.1 Volts?

Question 2: Will this be higher or lower that the frequency light emitted by a diode that turns on at 4.5 volts? Will the 2.1 volt diode be bluer or redder?

Question 3: Most diodes turn on at several tenths of a Volt. Why don't we see light from them?

Analysis Questions

Question 1: How does the slope to compare with the accepted value of Planck's constant, 6.626x10-34 Joules.s? Consider the uncertainty of the slope for this comparison.
