Lightning Flash is a term used to describe the phenomenon of lightning, which is a sudden and powerful electrical discharge that occurs during a thunderstorm. The term can be broken down into three parts: STREAK (6 letters), BOLT (4 letters), and THUNDERBOLT (11 letters). STREAK refers to the bright line of light that appears in the sky during a lightning flash, while BOLT is a term used to describe the electrical discharge itself. Finally, THUNDERBOLT is a term used to describe a particularly powerful lightning flash, which is often accompanied by a loud clap of thunder.
