Multiple Choice

Since there is no slope to this pattern the beam will be directed _______.

Explanation:
When a pattern has no slope, the energy sits symmetrically around the optical axis, so there’s no tilt to push the beam up, down, or off to the side. The beam therefore travels along the axis—straight ahead. If there were any slope, you’d see upward or downward deflection or an off‑axis shift, but zero slope means no angular deviation.
