Massage. Massage your muscles to relieve tightness. Use lotion or baby oil to decrease friction between your fingers and your skin while you massage. Apply firm but pain-free pressure and move slowly in a circular pattern along the length of the tight muscle.
Noun. 1. laser-an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light. optical maser. optical device-a device for producing or controlling 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.
