Imagine that you turn on the lamp in your room that contains an incandescent light bulb and that you stand 1m from the light. Suppose further that your bulb is rated at 100 W. What is the intensity of the light that passes out through this sphere at this distance of say 1m? Now compare this to a milliwatt laser at the same distance away. How many times more/less intense is the laser beam to your eye compared to the...
