Red is a primary color, you can't mix 2 to get red. Blue is primary, too, and so is yellow. You can mix any of the above colors to make another color. ie: red and yellow make orange. red and blue make purple. blue and yellow make green. yellow and green make light green. white and red make pink.
There are quite some differences between an optical mouse and a laser mouse. One of the most noticeable differences is the type of rays coming out of the mouse. Now,we all kâ¦now that from an optical mouse there is (usually) a red light coming out and on the other hand, the laser mouse does not produce such light.
A laser is different in three main ways: 1- The light emitted from a laser is monochromatic, that is, it only has one wavelength (color). Ordinary light on the other hand, is a combination of many different wavelengths (colors). 2- It is coherent, that is, the waves of light of the laser are in phase.Just like two sea waves when they are both at their maximum height, all waves of the light in a laser are exactly at the same amplitude, all time. 3- It is highly directional. Laser light is emitted as a narrow beam in a specific direction.- It is coherent, that is, the waves of light of the laser are in phase.
