All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure<span> of the angles, we know that the </span>sum<span> of all the angles is 1080 degrees (from above)... And there are eight angles... So, the </span>measure<span> of the interior angle of a regular </span>octagon<span> is 135 degrees</span>

Answer:
distance = 9.495 mm
Step-by-step explanation:
Given data
slits distance = 0.100 mm
viewing screen distance = 1.50 m
wavelength = 633 nm
to find out
how far apart are the bright fringes on the viewing screen
solution
we use here double slit diffraction condition that is
d sin(θ) = m λ .......................1
here m = 0, 1 , 2 , 3 .....
and here for θ small so
sin(θ) = tan(θ) =
so x = l sin (θ)
so from equation 1
x =
and
x1 = ...............2
x2 = ..............3
so distance x2 - x1 will be
distance =
distance =
distance = 9.495 mm
