How would a diffraction grating be useful to an astronomer? be specific.
Homework Answers
Diffraction gratings are very useful for accurately measuring the wavelength of light. Gases, for instance, give off light of particular colors - each element has its own characteristic fingerprint of emission lines. When astronomers look through diffraction gratings at stars, for instance, they can tell what elements the star is composed of by measuring the wavelengths of light they see (or the wavelengths of light missing from the spectrum). This is known as spectroscopy.

What is the differences between the zeroth order diffraction grating and first order diffraction grating in properties of the light? I think that this equation has the answer (( d'sin theta=n lambda )) So if the theta is 30 the lambda will be 1/2 what does that mean in the property of that light in first order? and is it possible for light of wavelength lambda to be zero? in case that theta was zero so sin 0=0 and this...

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...

An apparatus similar to the one used in this week's diffraction grating experiment is used to measure ruling density of a diffraction grating. A second order maximum is observed to be 3.796 m from the central maximum. The wavelength of the coherent, monochromatic light striking the grating is 567 nm. The distance from the double slit to the display screen is 1.77 m. What is the slit spacing of this diffraction grating? What is the ruling density of this diffraction...
