Calculate the power of light in the wavelength range

Interpretation:
The power of light in the wavelength range
Concept introduction:
Planck’s equation can also be represented in the form of power flux or infinitesimal power per unit area for a black body radiation at a given temperature and wavelengths as shown below.
Answer to Problem 9.32E
The power of light in the wavelength range
Explanation of Solution
It is given that wavelength range is
The formula to calculate the power of light is,
Where,
•
•
•
•
•
Substitute the values of constants and temperature
On simplifying the above equation,
Thus, the value of power flux is
Substitute the values of constants and temperature
On simplifying the above equation,
Thus, the value of power flux is
Substitute the values of constants and temperature
On simplifying the above equation,
Thus, the value of power flux is
The power of light at the temperatures
