In the experiment to measure the wavelength of a monochromatic light beam, the beam is directed at two slit Young apart

= 0,07 mm. Adjust the viewing screen position to the position two slits
a segment D = 1.5 m then the background interference on the screen.
a) The measured 5th order dark fringe position is y = 4.5 cm. Calculate the wavelength  of the light beam.
b) Calculate the distance from the 3rd order bright fringe to the 5th order dark fringe.
c) Calculate the number of bright fringes observed on the screen.

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.

mistakes are ok

inverse v=i*r
