Question

Figure below shows a double slit located a distance x from a screen, with the distance from the center of the screen given by y. The slits are illuminated by light of wavelength λ. When the distance d between the slits is relatively large, there will be numerous bright spots, called fringes.

1. Figure below shows a double slit located a distance x from a screen, with the distance from the
center of the screen given by y. The slits are illuminated by light of wavelength A. When the distance
d between the slits is relatively large, there will be numerous bright spots, called fringes.
Using the small angle approximation (where sine -0, with e in radians), calculate the distance
between fringes in terms of A and the variables shown below.
Ym+1
Ym
d
X
Answer symbollically using: x,d, and A. Use the orange square root symbol box to enter variables
and greek symbols.
Ay =
Using the result of part (a), calculate the distance between fringes for 665 -nm light falling on double
slits separated by 0.07 mm, located 4 m from a screen as in Figure.
Ay:
