Assignment:
Calculate the total power per unit area generated by a xenon lamp determined at 50 cm from the lamp by integrating the irradiance spectrum over the specified wavelength range of 250 - 400 nm. As the irradiance spectrum cannot be described analytically, convert the integral to a summation expression, and divide up the specified wave-length range in 6 bins (bin width = 25 nm). By summing, or numerically integrating, determine the total power per cm^2 generated 50 cm from the lamp. As an extra exercise, determine the total power per cm^2 generated at the lamp. Show the steps involved and explain your work.
Provide complete and step by step solution for the question and show calculations and use formulas.
