Atopaz crystal has an interplanar spacing (d) of 1.36 å (1 å =1×10^[−10] m). calculate the wavelength of the x-ray that should be used if θ = 15° (assume n = 1).

7.0*10-11m or 70Å

Explanation:

From Bragg's equation, w=2dsinx/n

Since all the parameters are specified in the question, we can easily go ahead to obtain the wavelength but we must convert the spacing given in angstroms to meters using the conversion factor provided as shown in the solution below:

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
