Each of the four parts of this problem depicts a motion diagram
showing the position and velocity of a charged particle at equal
time intervals as it moves through a region of uniform electric
field. For each part, draw a vector representing the direction of
the electric field.
Draw a vector representing the direction of the electric
field. The orientation of the vector will be graded. The location
and length of the vector will not be graded.

Below is a ray diagram showing the refracted ray as it travels
across the diamond. The dashed line represents the normal to the
surface between the water and the diamond.
though you don't know the exact direction of the incident ray
yet, you can estimate it by applying step 3 in the Tactics Box
above. Use your estimate to complete the ray diagram.
