Putting the values from the question in the formula:

$\mathrm{\u25b3}\lambda =\frac{6.62\cdot {10}^{-34}(1-\mathrm{cos}({115}^{\circ}))}{9.1\cdot {10}^{-31}\cdot 3\cdot {10}^{8}}\phantom{\rule{0ex}{0ex}}=0.345\cdot {10}^{-11}\text{}m\phantom{\rule{0ex}{0ex}}=3.45\text{}pm$

there will be the change of 3.45 pm in the wavelength.

If an x-ray source has an activity of ${10}^{9}$ becquerel then by the relation:

$Number\text{}of\text{}photons=Activity\ast yield$

is the Number of photons equal to ${10}^{9}$ ?

$Number\text{}of\text{}photons=Activity\ast yield$
