WebSep 12, 2024 · Figure 6.2. 2: The intensity of blackbody radiation versus the wavelength of the emitted radiation. Each curve corresponds to a different blackbody temperature, starting with a low temperature (the lowest curve) to a high temperature (the highest curve). The intensity I ( λ, T) of blackbody radiation depends on the wavelength λ of the emitted ... WebJan 7, 2024 · In addition, the difference in the optical calculation is small for long wavelengths. For a 400-nm wavelength, the difference reaches 30% and 200% for the transverse and axial forces, respectively. Finally, we compared the optical force with various beam waists. In this simulation, the particle size is 100 nm.
