- Can we obtain both large depth of field and high resolution in optical microscope? How does it compare to the electron microscope? Explain the difference.4. The graph below shows the wavelength of light for two stars as a function of their power density, one of the sun and the other being our next closest star, Proxima Centauri. Sun Proxima Centauri Wavelength (nm) (a) Does the sun or Proxima Centauri have a greater surface temperature? Explain your answer. Power Density (1013 watts/m³)3. Suppose we wish to do a double-slit experiment with a beam of smoke particles of mass 10-9 g moving at 1 cm/s. Assume we can construct a double slit whose separation is about the same size as the particles. Estimate the separation between the fringes if the double slit and the screen were on opposite coasts of the United States.
