Find the change in radar cross section area of a cylindrical aero plane at different frequency bands, starting from L band to Ku band, and if diameter is 5meters, and length is 4 times the diameter. Prepare a table of values for all bands from L to Ku, with row values, frequency, wavelength and Cross section area. Analyze the values and give your understanding.

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

Radiation flux and separation distance lab Formula : Counts/Second = Crn C = 4700 counts/second. n = -2.43, detector window area = 1cm^2 Determine the source activity using these values.

In order to observe emissions from celestial bodies Very Long Baseline Arrays (VLBA) have been developed. Explain why VLBA use multiple telescopes separated by long distances in terms of the wave nature of light. Include in your answer specific physics terminology, associated relevant equations, and a labelled diagram.
