To determine which metal has a smaller threshold wavelength based on the given information, we can follow these steps: ### Step 1: Understand the relationship between frequency and wavelength The threshold wavelength (\( \lambda_0 \)) is related to the threshold frequency (\( \nu_0 \)) by the equation: \[ \lambda_0 = \frac{c}{\nu_0} \] where \( c \) is the speed of light. This shows that the wavelength is inversely proportional to the frequency. ...
