Question

a) let v be the maximum speed of the emitted photoelectrons, and n be the number of photoelectrons emitted per seond. If the filter is changed from orange to yellow, then:
v increases, n remains the same
v remains the same, n increases
v remains the same, n remains the same
v decreases, n remains the same
v increases, n decreases
v increases, n increases
v remains the same, n decreases
v decreases, n increases
v decreases, n remains the same

b) If the laser you used is replaced by a much brighter laser, then
v decreases, n increases
v decreases, n remains the same
v remains the same, n increases
v increases, n remains the same
v decreases, n remains the same
v increases, n increases
v remains the same, n decreases
v remains the same, n remains the same
v increases, n decreases

Explanation / Answer

yellow has shorter wavelength than orange so velocity increase, n remains same
answer is v increases, n remains the same

velocity stays same and n increases...more power = more electrons emitted
