Hans observed properties of four different waves and recorded observations about each one in his chart.

which statement is best supported by the table?

wave w is being reflected, wave x is being refracted, and waves y and z are being diffracted.
wave x is being diffracted, wave z is being reflected, and waves y and w are being refracted.
wave x is being reflected, wave z is being refracted, and waves y and w are being diffracted.
wave w is being diffracted, wave x is being reflected, and waves y and z are being refracted.

The correct answer is Wave W is being diffracted, Wave X is being reflected, and waves Y and Z are being refracted.

Wave X is bouncing off the surface thats why it is being reflected. As the waves pass from one medium to another they change speed i.e. when passing through water into air. This causes waves to bend and change color hence waves X and Z. The scattering of waves through a small opening is called diffraction so wave W

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.
