How do you ensure that the laser is “parallel” to the ground and that the pointer is not adjusting the beam to contact the target thus defeating the measurement variable
A level plane, a bubble I. A tube. Making a level surface is not a difficult task, and may be done for this experiment. There are many ways to measure 90 degrees when building an experiment.
