    Bragg's law Law
AI Thread Summary
Bragg's Law, represented by the equation 2dsinθ = nλ, is primarily used to determine the wavelength of x-rays by measuring the diffraction angle and knowing the crystal lattice spacing. It can also derive structural parameters, such as distances between electron densities, using a known wavelength. This equation is essential in diffraction experiments like X-ray diffraction (XRD) and small angle x-ray scattering (SAXS). Additionally, it allows for the calculation of angles for specific structures and wavelengths, aiding in the design of x-ray monochromators. Bragg diffraction also plays a role in determining the mass of the pi-meson through atomic transition x-ray energy measurements.

In the Bragg's Law, what is the equation 2dsinθ = nλ actually used to find?
 
Physics news on Phys.org
It is normally used to determine the wavelength of an x-ray by knowing the crystal lattice spacing and measuring the diffraction angle..
 
... it can also be used the other way round - i.e. to derive structural parameters from a sample, e.g. distances between electron densities (=d) using a known wavelength (=lamda).
This is used in diffraction experiments (XRD) like in crystallography or in small angle x-ray scattering (SAXS).
 
And finally, it can be used to calculate the angle(s), for a given structure and wavelength. So you can design an x-ray monochromator, for example.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
