Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference minima at \pm 35.09 degrees on either side of the central bright spot. you then immerse these slits in a transparent liquid and illuminate them with the same light. now you find that the first minima occur at \pm 19.48 degrees instead.
a) what is the index of refraction of this liquid?
express your answer using four significant figures.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

as technology advances, new experiments often expose problems in accepted theories. c
