Identify the correct relation connecting the work function

\phi

, Planck constant

h

, speed of light

c

, and threshold wavelength

\lambda_0

of a photosensitive surface. (a)

\phi = \dfrac{h c}{2\,\lambda_0}

(b)

\phi = \dfrac{2 h c}{\lambda_0}

(c)

\phi = \dfrac{h c}{\lambda_0}

(d)

\phi = \dfrac{3 h c}{2\,\lambda_0}
