Photoemission Calculations

Calculating Photon Energy

• To calculate the energy of a photon, we can use the following formula:
• Energy of Photon (E) = Planck's constant (h) × Frequency of Photon (ν)
• Given that the frequency (ν) of the photon is , we can calculate the energy of the photon using the formula:
• E = h × ν
• Substituting the known values:
• E = (6.626 × 10^-34 J·s) ×

Calculating Minimum Photon Frequency

• The minimum frequency (threshold frequency) required to cause photoemission can be calculated using the formula:
• Minimum Frequency (ν_min) = Work Function of Metal (Φ) / Planck's constant (h)
• Given that the work function of sodium metal (Φ) is , we can calculate the minimum frequency (ν_min) using the formula:
• ν_min = Φ / h
• Substituting the known values:
• ν_min = (2.28 × 10^-19 J) / (6.626 × 10^-34 J·s)
