Question

We have a plane wave (632.8 nm) that is travelling
along the z-direction. We also have a plane wave that is travelling
at an angle θ relative to the z-axis. For angles θ=π/6,θ=π/4 and
θ=0, using Matlab, plot the combined wave (for a fixed time) and
the intensity of the combined wave.

If we move a refrigerator magnet back and forth, we generate an
electromagnetic wave that propagates away from us. Assume we move
the magnet along the z-axis centered on the origin with an
amplitude of 10 cm and with a frequency of 2.0 Hz. Consider a loop
in the xy-plane centered on the origin with a radius of 2.0 cm.
Assume that when the magnet is closest to the loop, the magnetic

1. For a stationary ball of mass m = 0.200 kg hanging from a
massless string, draw arrows (click on the “Shapes” tab) showing
the forces acting on the ball (lengths can be arbitrary, but get
the relative lengths of each force roughly correct). For this case
of zero acceleration, use Newton’s 2nd law to find the
magnitude of the tension force in the string, in units of Newtons.
Since we will be considering motion in the horizontal xy plane,...
