Select the correct statement(s) regarding SMF and MMF fiber optic cables. a. multimode fiber (MMF) has a wider core diameter that supports multiple modes of light; as such, MMF can support higher data capacities compared to single-mode fiber (SMF)
b. MMF suffers from modal delay, which results in digital signal distortion
c. SMF cables are constructed with a small optical core, which means its data capacity is much less than MMF fiber which have a larger diameter core
d. all are correct statements

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
