I was asked this question by a student and would like to give a knowledgeable response, how should I respond to the following question:
"I would like to experiment with blue, red, and green 5mw lasers pointer pens for my physics class to use in diffraction experiments. I want to use these with diffraction glasses rated at 500 lines. They will pass through a diffraction grating and shine them on the other side of the wall in the classroom to measure the distance between maxima.. I know that most of the red lasers that I own are less than 5mW. Are these too powerful for this type of experiment?"
