Why is the laser red or green?
A: The difference between red laser and laser green laser Light is a red laser with a longer wavelength (about 650 nanometers) than a green laser (about 532 nanometers). The mechanisms that make them are also different. Red lasers use diodes, optics, and some electronics.
Can a laser pointer reach the moon?
