Calculate the maximum wavelength, \(\lambda_{\text{max}}\), of electromagnetic radiation that could eject electrons from the surface of aluminum, which has a work function of \(6.50 \times 10^{-19}\) J.

\[
\lambda_{\text{max}} = \boxed{3.06 \times 10^{-7}} \text{ m}
\]

If the maximum speed of the emitted photoelectrons is \(4.09 \times 10^6\) m/s, what wavelength of electromagnetic radiation struck the surface and caused the ejection of the photoelectrons?

\[
\lambda = \boxed{\phantom{3.06 \times 10^{-7}}} \text{ m}
\]
