An electron is launched from a plate of metal with a work function of 4*10^-19 J using light at a frequency of 5*10^15 Hz. Suppose that an ejected electron comes into contact with an H+ nucleus. Would the electron be bound or unbound? Sketch a plot of effective potential for hte orbit and mark on […]

My professor asked these questions in class yesterday and didn’t explain them well. Can you explain them to me? (a) Recall that microwave ovens heat your food by bombarding it with radiation at frequencies between .1 to 10 cm-1. What type of molecular transitions are excited in water to heat your food? (b) What is the […]
