Let's consider the sun to act like an ideal thermal radiator at a temperature of 6000 K.(a) At what wavelength does the sun emit its peak intensity? In what part of the electromagneticspectrum does this wavelength reside? Comment on how this wavelength compares with the peaksensitivity of the human eye. (You may need to look this up somewhere.)(b) Consider an interval of width d) = 2.0 nm centered on the wavelength you found in part (a). Whatis the intensity of the solar radiation emitted within this range? (Hint: You can use the approachof Example 3.6 on page 87 of our textbook.(c) What fraction of the total solar radiation does this represent?

The figure below depicts spectral reflectance measurements for three different materials: a green leaf from a healthy plant, a sheet of shiny blue paper, and the palm of a human hand. The measurements are labeled 1 (black line), 2 (red line), and 3 (blue line). Match the measurements to the most appropriate material type
The electric field has been measured to be horizontal and to the right everywhere on the closed box as shown in the figure below.
