Consider an electric circuit containing a light-sensitive element with a work function of 2.80 10^19 J. Monochromatic light of wavelength 7.00 10^7 m is shone on the light-sensitive element in a beam with a constant power of 2.50 10^3 W. Suppose that the incident beam power is held constant, but the wavelength is increased from its initial value of 7.00 10^7 m. Sketch how the electric current will change with the wavelength
