Ajani is trying to experimentally measure Planck's constant h. He does this by shining different wavelengths of monochro- matic (i.e., single-wavelength) EM radiation on a metal plate with unknown work function W, and then measuring the stop- ping voltage required to bring the ejected electrons to a halt. When he uses d1 = 400 nm, he finds that a stopping voltage of V1 = 0.7 V is required. When he uses X2 = 500 nm, he finds that a stopping voltage of V2 these two data points, what is Ajani's measurement of Planck's %3| 0.2 V is required. Based on constant?

He does this by shining different wavelengths of monochro-
matic (i.e., single-wavelength) EM radiation on a metal plate
with unknown work function W, and then measuring the stop-
ping voltage required to bring the ejected electrons to a halt.
When he uses d1 = 400 nm, he finds that a stopping voltage
of V1 = 0.7 V is required. When he uses A2 = 500 nm, he finds
that a stopping voltage of V2
0.2 V is required. Based on
these two data points, what is Ajani's measurement of Planck's
constant?
