Use the displacement law, peak wavelength = 0.0029/T =0.0029/30000 = 97nm
The answer is : <span>A model could be used to test his design in a lab. </span>Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm.
