Two light sources are utilized in a photoelectric experiment to decide the work function for a particular metal surface. When green light from a mercury lamp (λ = 546.1 nm) is utilized, a stopping potential of 0.930 V reduces the photocurrent to zero.

1. Based on this measurement, what is the work function for this metal?

-----------eV

2. What stopping potential would be observed when using light from a red lamp (λ = 634.0nm)?

------------V
