Find the distance between atomic planes. Assume that n=1, the angle of reflection is 45.0 degrees, and the wavelength of x-rays
used in the experiment in 1.54 Å.

What is the distance between the atomic planes?

a. 0.905 Å

b. 1.098

c. 0.544 Å

d. 0.655

e. 0.918 Å

f. 1.11 Å

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
