Concept explainers
Interpretation:
The wavelength of the orange line from the figure needs to be determined and also determine the frequency and energy of the photon.
Concept introduction:
A photon is a massless particle conveying a quantum of energy. Energy of a photon is calculated by formula
Answer to Problem 50A
Frequency is
Explanation of Solution
From the given figure, the wavelength is approximately
The speed of an
Convert nanometer into meter as follows:
The value of speed is
Substitute above values in equation (1).
Hence, frequency is
Now, calculate energy of the photon by the expression given below:
The value of h is
Substitute the value of h and frequency in equation (2) as follows:
Hence, energy is
Frequency is
