(a) Find the kinetic energy (in eV) of an electron whose deBroglie wavelength is equal to 0.5 Å = 0.05 nm, a typical atomicsize
When UV light of wavelength 255 nm falls on a metalsurface, the maximum kinetic energy of emitted electronsis 1.40 eV. What is the work function of the metal?
b) A metal is impacted by photons of wavelength 375 nm and electrons are emitted from its surface. Given that the work function of the metal is 2.5 x 10-1⁹ J, calculate: i) The maximum kinetic energy of the emitted electrons. ii) The maximum speed of the electrons. c) In a Millikan oil drop experiment a charged oil droplet of mass 8.22 x 10-16 kg is held stationary by the electric field between two oppositely charged horizontal parallel plates a distance 50.0 mm apart. The top plate is at a potential of +840 V with respect to the lower plate and the acceleration due to gravity g is 9.8 ms ². i) Calculate the charge on the droplet and state its nature. ii) Calculate the initial acceleration of the droplet if the plate voltage is suddenly reversed.
