Specify a natural phenomenon that exhibits a spectrum of a white-light source (similar to the spectrum of an incadescent lamp viewed with diffraction grating). How is it formed? Does it also possess higher-order spectrums? Explain.
Homework Answers
Rainbow is one of such natural phenomenon.
It's primarily formed by the phenomenon of refraction , reflection and dispersion of light from the sun when it impinges the droplets of water.More details of it can be found by referring any standard physics text on subject or searching on web.

The atomic emission spectrum of a light source is analyzed with a diffraction grating. A thick line near 589.0 nm is observed. In order to resolve the thick line into two fine lines in first order, you replace with a 2.450 cm long diffraction grating, and you barely observed two distinct first order spectral lines at 589.0 and 589.6 nm on a screen 5.000 m away. a. What is the resolving power of the grating? b. What is the slit...

White light is spread out into its spectral components by a diffraction grating
White light is spread out into its spectral components by a diffraction grating. If the grating has 2000 lines per centimeter, at what angle does red light of wavelength 640 nm appear in first-order spectrum? (Assume that the light is incident normally on the grating.) Unpolarized light passes through two Polaroid sheets. The transmission axis of the analyzer makes an angle of 43.4° with the axis of the polarizer. (a) What fraction of the original unpolarized light is transmitted through the analyzer?...
