Aplane wave with a wavelength of 500 nm is incident normally ona single slit with a width of 5.0 × 10–6 m. consider waves that reach a point on a far-away screen such thatrays from the slit make an angle of 1.0° with the normal. thedifference in phase for waves from the top and bottom of the slitis:
a) 0
b) 0.55 rad
c) 1.1 rad
d) 1.6 rad
e) 2.2 rad

To solve this exercise it is necessary to use the concepts related to Difference in Phase.

The Difference in phase is given by

Where

Horizontal distance between two points

Wavelength

From our values we have,

The horizontal distance between this two points would be given for

Therefore using the equation we have

Therefore the correct answer is C.

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:

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
