An experiment is conducted to investigate the photoelectric effect using two different metal plates, Metal 1 and Metal 2, whose work functions satisfy \(\Phi_1 < \Phi_2\). Monochromatic light of wavelength \(\lambda\) shines on each metal target, producing photoelectrons with measured stopping potentials of \(V_1\) and \(V_2\), respectively.

Target Metal	Work Function	Measured Stopping Potential
Metal 1	\(\Phi_1\)	\(V_1\)
Metal 2	\(\Phi_2\)	\(V_2\)

The experiment is then repeated using monochromatic light with half the original wavelength, \(\frac{\lambda}{2}\). How does the new stopping potential \(V_1'\) for Metal 1 compare to \(2V_1\), and how does the new difference in stopping potentials \((V_1' - V_2')\) compare to the original difference \((V_1 - V_2)\)?
