If electrons are ejected from a metal when yellow light is shone on it, explain, using...
Light striking a metal surface causes electrons to be emitted from the metal via the photoelectric effect.In a particular experiment to study the photoelectric effect, the frequency of the incident light and the temperature of the metal are held constant. Assuming that the light incident on the metal surface causes electrons to be ejected from the metal, what happens if the intensity of the incident light is increased?Check all that apply.The work function of the metal decreases.The number of electrons...
Could you please explain in detail so that I understand it completely, I'm not very familiar with science. Thank you! 8.(9 pts) Consider a metal for which the photoelectric effect is possible with a maximum wavelength in the blue region of the spectrum. Infrared, red, yellow, violet and ultraviolet beams are successively directed at the metal. a. Which, if any, of these "colors" will cause electrons to be ejected from the surface and why? b. Which beam will result in...
The wavelength required to dislodge electrons from a certain metal via the photoelectric effect is 350 nm. When light of an unknown wavelength is shined upon the metal, electrons with kinetic energy of 150 kJ/mol are emitted. What is the wavelength of the light?

11. If a metal surface is irradiated with 185 nm light, electrons are ejected with a velocity of 8.90 x 105 m/s. What is the minimum frequency (in Hz) of light that could be used which will still eject electrons from the surface?
(b) (12 pts) We conduct a photoelectric effect experiment where the electrons are ejected from a metallic surface with speeds of up to vo when light with a wavelength Xo is used. Suppose we now use light with a wavelength 70/2. What will be the maximum speed of the electrons ejected from the metallic surface?

1) When a light with a of wavelength 350 nm is shone on metallic rubidium, electrons are ejected. a) calculate the kinetic energy of one such electron, given the threshold wavelength of rubidium is 1600 nm. b) State the name of and explain the specific theory behind your calculation 2) Write the condensed electron configuration for Bromine.
In the photoelectric effect experiment, a beam of light is shining on a metal surface and the electrons are emitted from the metal. One of the three key findings is that a minimum frequency of light is required for emission of electrons. This minimum frequency is found to be 5.5 × 1014 s-1 for an unknown metal. 4 Briefly describe the other two findings and draw a plot fo the KE of emitted electrons against light frequency. (a) (6 marks)...
