Question

Fill out the tables

rocedure: For each target m sodium , copper, platinum, calcium, unknown), determine the maximum wavelengin (minimum frequency) necessary for photoelectrons to be emitted. Use c tA to calculate the frequencies and find the work function. ThresholdWork Function Sample Frequency x 101" Hz 5576 10.452 11.450 (eV) 2.306 4.322 4.735 | Sodium Zinc Copper 2. Determining Planck's Constant Procedure: For each table, choose the specified target metal and find the stopping potential for 9 different wavelengths that cause photoelectrons to be emitted ITarget Metal: Zinc Wavelength, nm Wavelength, m Frequency, Hz Stopping Potential, Insert graph here. lll. Target Metal: Copper elength, nm Wavelength, m Frequency, Hz Stopping Potential,

Answer 1

mous t 2.1 8.1nm 26.2 nm he which can also be Caltulatol

And please try to fill the table yourself.

Don't be such a lazy dear.

And for your information no one will fill out the table.
