If the interplanar distance in the crystal is 287 pmpm , and the angle of maximum reflection is found to be 7.28 ∘∘, what is the wavelength of the x-ray beam? (Assume n=1n=1.)

The wavelength of X-ray is

Explanation:

To calculate the wavelength of the radiation, we use the equation given by Bragg, which is:

where,  

n = order of diffraction = 1

= wavelength of the X-ray = ?

d = spacing between the crystal planes =      (Conversion factor:   )

= angle of diffraction = 7.28°

Putting values in above equation, we get:

Hence, the wavelength of X-ray is

8 carbon atoms forming single bonds with 18 hydrogen atoms; a triple bond exists between the third and fourth carbon atom from the right

explanation:

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
