A photon of green light has an energy of 2.5 eV. What is its frequency? (h = 4.14 10^(-15) eVs)

Answer and explanation

Correct answer: C. 6.04 * 10^14 Hz

  1. Step 1: Apply Planck's equation: E = h * f => f = E / h.
  2. Step 2: Substitute given values: f = 2.5 eV / (4.14 10^(-15) eVs).
  3. Step 3: Compute: f approx 0.60386 10^15 Hz = 6.04 10^14 Hz.
Answer
6.04 * 10^14 Hz.
Why not the others: '3.77 10^14 Hz' multiplies by 1.5; '1.66 10^15 Hz' inverts the quotient; '1.04 * 10^14 Hz' calculates with incorrect powers.
