Variation of radiant energy `Elambda` emitted by sun, filament of tungsten lamp and welding arc as a function of its wavelength as shown in the figure. Which of the following option is the correct match ?

Options

A. Sun-`T_(1)`, tungsten filament- `T_(2)` , welding arc-`T_(3)`
B. Sun-`T_(2)`, tungsten filament- `T_(1)` , welding arc-`T_(3)`
C. Sun-`T_(3)`, tungsten filament- `T_(2)` , welding arc-`T_(1)`
D. Sun-`T_(3)`, tungsten filament- `T_(1)` , welding arc-`T_(2)`

Answer

D

Explanation

The temperature of sun is a higher than that of welding arc which in turn greater than tungsten filament.
