When blue light (450 nm) is shone on a particular metal surface, electrons are ejected within a kinetic energy of 2.5 x 10^-20J.

a. Calculate the work function for this metal.
b. Will green light (500 nm) cause an electron to be ejected?
c. What is the longest wavelength light that will eject an electron?

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?
