Burnt filament of a light bulb. Coloured Scanning Electron Micrograph (SEM) of the double coiled tungsten wire filament of a light bulb,after burning out. The broken coiled filament lies beside the wire posts of the light bulb. Tungsten is a heavy metal with an extremely high melting point and thus widely used in light filaments. With repeated use,however,the tungsten wire eventually breaks ending the life of the light bulb. Magnification: x21 at 6x7cm size. x58 at 7x8 inch size | |
