When a monochromatic ultraviolet light with a wavelength of 254 nm falls onto the surface of a particular metal it causes a photocurrent to flow. A stopping voltage of 2.30 V is required to totally block the photocurrent.
a. What is the work function of the material?
W = _______ eV
b. What is the cutoff wavelength for this metal?
λ = ________ nm
c. Will light with a wavelength of 523 nm be able to cause a photocurrent from this material?
