Question

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

Sun- $T_{1},$ tungsten filament $- T_{2},$ welding arc $- T_{3}$
Sun $- T_{2},$ tungsten filament $- T_{1},$ welding arc $- T_{3}$
Sun $- T_{3},$ tungsten filament $- T_{2},$ welding arc $- T_{1}$
Sun $- T_{1},$ tungsten filament $- T_{3},$ welding arc $- T_{2}$

The correct answer is: Sun $negative T subscript 3 end subscript comma$ tungsten filament $negative T subscript 2 end subscript comma$ welding arc $negative T subscript 1 end subscript$
