Like most common beans, they are native to the Americas, but have been introduced around the world. They are also used in East Indian cooking, Punjabi cuisine and are referred to as black beans and in Maharshtrian cuisine known as ``Kala Ghevada''. They are used interchangeably with vigna mungo in countries such as the US.

If a screen is placed in the plane of a real image the image will generally become visible on the screen. Examples of real images include the image seen on a cinema screen (the source being the projector), the image produced on a detector in the rear of a camera, and the image produced on an eyeball retina (the camera and eye focus light through an internal convex lens). In ray diagrams (such as the images on the right), real rays of light are always represented by full, solid lines; perceived or extrapolated rays of light are represented by dashed lines. A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to converge.
