Answer:
Index of refraction=Angle of incidence/Angle of refraction
=5/2.1
=2.38
Answer:
Explanation:
y = Distance from the center point
d = Separation between slits = 0.3 mm
D = Distance between slit and screen = 1.5 m
= Wavelength = 700 nm
m = Order = 1
We have the relation
The distance from the screen at which the first bright fringe beyond the center fringe appear is .
On that list of choices, 'C' is the only "example" of a plane.
None of the choices "describes" a plane.
