Answer to Problem 4.1P
The graph for the function
Explanation of Solution
Given:
The Planck distribution function for blackbody
Calculation:
Consider the term,
The value of the term is calculated as,
Consider the term,
The value of the term is calculated as,
Thus, the Planck's distribution function of a blackbody radiation for a fixed temperature
The following table shows the Planck's intensity distribution for different wavelengths at a fixed temperature.
Wavelength | |
The following figure shows the Planck's intensity distribution for different wavelengths at a fixed temperature.
Figure (1)
From the graph, it can be concluded that the intensity of blackbody radiation for a fixed temperature, is maximum at a particular wavelength and it becomes zero with the increase in wavelength. With the increase in temperature, the maximum intensity of a radiation shift towards the shorter wavelengths.
Conclusion:
Therefore, the graph for the function
