#1 yes they traveled the same distance
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
These are expression written as a function of sine, cosine and tangent. The value of x from the given function is 4.29
Trigonometry expression
These are expression written as a function of sine, cosine and tangent.
Given
tanx² - 1/3 = 0
Add 1/3 to both sides
tanx² - 1/3 + 1/3 = 0 + 1/3
tanx² = 1/3
x² = arctan(1/3)
x² = 18.44
x =4.29
Hence the value of x from the given function is 4.29
