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
