Problem

An experimental plot of photon wavelength shift

\Delta \lambda

versus

(1 - \cos \theta)

yields a straight line with slope

S = 2.46\,\text{pm}

. Using

m_e = 9.11 \times 10^{-31}\,\text{kg}

and

c = 3.00 \times 10^8\,\text{m}\,\text{s}^{-1}

, determine the corresponding experimental value of Planck's constant

h

(in

\text{J}\,\text{s}
