All are intended to be at the college level. Each AP Physics course has an exam for ...
Astral projection (also known as astral travel, soul journey, soul wandering, spiritual journey, spiritual travel) is a term used in esotericism to describe an intentional out-of-body experience (OBE) that assumes the existence of a subtle body, known as the astral body or body of light, through which consciousness can function separately from the physical body and travel throughout the astral ...
White light is dispersed by a prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light). The optical spectrum is sometimes considered to be the same as the ...
In astronomy, seeing is the degradation of the image of an astronomical object due to turbulence in the atmosphere of Earth that may become visible as blurring, twinkling or variable distortion. The origin of this effect is rapidly changing variations of the optical refractive index along the light path from the object to the detector.
Glory around the shadow of a plane. The position of the glory's centre shows that the observer was in front of the wings. A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds.
