Question

# Why is the tungsten used almost exclusively for filament of electric bulb.

Solution

## Tungsten has the highest melting point $$(3695 K)$$ , lowest vapour pressure and greatest tensile strength among all the metals. It can reach higher temperatures before melting and hence can emit brighter light.  Also , the light emitted due to heated tungsten lies in the visible spectrum and is yellow in colour which makes it the most preferred material for  filament of electric bulbs.Physics
