To calculate the energy of a photon what two values are multiplied together?Select answer from the options belowfrequency (ν) and wavelength (λ)frequency (ν) and Plank's constant (h)speed of light (c) and Plank's constant (h)speed of light (c) and wavelength (λ)wavelength (λ) and Plank's constant (h)

An LED that emits light of wavelength λ = 449 nm illuminates the phototube. A reverse bias is applied to the phototube (a voltage that opposes the current flow). This is adjusted carefully until the photocurrent drops to zero. The stopping potential is found to be Vo = 1.086 V.The LED can now be changed and the process repeated for a different λ. Then the data can be plotted to determine Planck's constant, h.For the data collected above what value would you plot on the x-axis of your graph? (Use c = 3.00 x 108m/s.)Express your answer in SI units to 3 significant figures.Entering numbers in scientific notation: Example: 1.45 x 10-9 should be entered as 1.45E-9
