A black body is an object that absorbs incident radiation across all wavelengths (thus it is called a black body) and emits thermal radiation across a continuous frequency spectrum based on the object's temperature. Planck's law is: 2πc²h R(A,T) = 25 1 (hc)/(AKT) - Where is the wavelength in meters, c = 3 x 10^8 meter/second is speed of light, h = 6.63 x 10^-34 Joule-second is Planck's constant, and k = 1.38 x 10-23 Joule/Kelvin is Boltzman's constant Task 1 X Using Planck's law, write a MATLAB script to plot the spectral radiance of a black body at T-5700 degrees x Celsius from 0 to 2000 nanometers (ns). Label the x-axis, y-axis, and the title of your plot correctly with x units.
