To find the work function of the metal in electron volts when exposed to light of different wavelengths, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We have two scenarios with different wavelengths of light. When light of wavelength 600 nm is used, the maximum kinetic energy of the emitted electrons is \( K_{max} \). When the wavelength changes to 400 nm, the maximum kinetic energy doubles to \( 2K_{max} \). 2. **Use the Photoelectric Effect Equation**: ...
