6. Light with a frequency of 2.37 x 1015 Hz ejects electrons from the surface of platinum, which has a work function of 6.53 eV. What is the minimum de Broglie wavelength of the ejected electrons? nm
When light hits a surface of a vacuum photocell with light of wavelength 555 nm electrons are barely ejected from the surface. You change the excitation wavelength to 401 nm. Calculate the ejected electrons kinetic energy and velocity. I would need the complete solution to understand the answer. Many thanks
When light with a wavelength of 216 nm is incident on a certain metal surface, electrons are ejected with a maximum kinetic energy of 3.35 × 10-19 J. Determine the wavelength of light that should be used to double the maximum kinetic energy of the electrons ejected from this surface. in m/s with 3 sig figs please
When light with wavelength 740 nm shines on a particular sheet of metal, it ejects electrons that have a maximum kinetic energy of 0.4 eV . What is the maximum kinetic energy of ejected electrons if we shine light with wavelength 380 nm on the sheet of metal instead?

2. Radiation of a certain wavelength causes electrons with a maximum kinetic energy of 0.70 eV to be ejected from a metal whose work function is 2.70 eV. What will be the maximum kinetic energy with which this same radiation ejects electrons from another metal whose work function is 2.15 eV? eV
Electromagnetic radiation is incident on a metallic surface. Electrons are emitted from the surface when the wavelength is 450 nm or less. a) What is the work function of the metal? b) What is the maximum kinetic energy of photo-electrons if the incident light has a wavelength of 400 nm? c) What is the stopping voltage required to stop photo-electrons ejected by the plate when the incident light has a wavelength of 300 nm? d)If the stopping voltage is 5...
