3. Generate the plot of spectral energy density vs frequency and spectralenergy density vs wavelength for both the Rayleigh-Jeans formula (RJF)and Planck's radiation formula (PRF) from 250nm to 2500 nm using MSExcel or any programming (this range includes the visible light from 400nm to 700 nm) for 1200 K and 1800 K temperatures. Discuss the resultingplots. Label the peaks (wavelength or frequency) for each plot.a. RJF (x-axis frequency) at T=1200 K and 1800 Kb. PRF (x-axis wavelength) at T=1200 K and 1800 Kc. RJF and PRF (x-axis frequency) at T =1800 Kd. RJF and PRF (x-axis wavelength) at T =1800 K

The Balmer series, or Balmer lines in atomic physics, is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is due to transitions of electrons to the energy level with n=2. Using the ideas and treatment seen in class, find the three largest wavelengths corresponding to lines of the Balmer series. Express your results in nm.
