If a photon has energy of 5 eV, what is its corresponding frequency?

If a photon has energy of 5 eV, what is its corresponding frequency?

Step 1: Understand that we need to find the frequency (ν) of a photon given its energy (E).
Step 2: Recall the formula that relates energy and frequency: ν = E/h, where h is Planck's constant.
Step 3: Identify the values: E = 5 eV and h = 4.14 x 10^-15 eV·s.
Step 4: Substitute the values into the formula: ν = 5 eV / (4.14 x 10^-15 eV·s).
Step 5: Perform the division: 5 / (4.14 x 10^-15) to calculate the frequency.
Step 6: The result of the calculation gives you the frequency: ν = 7.5 x 10^14 Hz.

Photon Energy and Frequency Relationship – The relationship between the energy of a photon and its frequency is given by the equation E = hν, where E is energy, h is Planck's constant, and ν is frequency.
Unit Conversion – Understanding the need to convert energy units (eV to Joules) if necessary, although in this case, the units are consistent.
