When light meets a water droplet, it is refracted at the boundary of air and water, and enters the droplet, where the light is dispersed into the seven colors. The rainbow effect occurs because the light is then reflected inside the droplet and finally refracted out again into the air.hen light meets a water droplet, it is refracted at the boundary of air and water, and enters the droplet, where the light is dispersed into the seven colors.

Valium belongs to a class of drugs called benzodiazepines, which work by increasing the effects of GABA, a neurotransmitter that moderates the activity of nerve signals in the brain. The Food and Drug Administration (FDA) approved diazepam in 1963 under the brand name Valium for the Roche drug company.
Valium is a potential drug of abuse that can result in problems like physiological dependence, tolerance, and addiction when used for an extended period of time, at high doses, or for reasons other than prescribed. Having a legitimate prescription does not eliminate the potential for abuse.
