To determine whether sodium shows photoelectric emission for orange light with a wavelength of \( \lambda = 6800 \, \text{Å} \), we need to follow these steps: ### Step 1: Convert the wavelength from angstroms to meters 1 angstrom (Å) = \( 10^{-10} \) meters, so: \[ \lambda = 6800 \, \text{Å} = 6800 \times 10^{-10} \, \text{m} = 6.8 \times 10^{-7} \, \text{m} \] ...
