Dear all, hope you can help me resolve my doubts.
1) If a laser can light up a paper in 10m, can the same laser light up the paper in 100m? Does distance play a role here?
2) Is a 100mw red laser as powerful as a 100mw green laser in terms of burning ability?
3) Is there any reliable seller in taobao/china which sell strong laser at low price?
