Question

8. calculate the peak emittance wavelength of an
object with surface temperature 6000k ?
(a) 4.85mm
(6) u83 pn nm
ce) 483 mm
(d) 48.3 mm​

Answer 1

around 500 nm

In the above example, the 6,000 K object has peak emission at around 500 nm, well in the visible band whereas the 4,000 K object peaks at just below 780 nm in the infrared.

Answer 2

Answer:

483nm

Explanation:

by win displacement law,

wavelength = b / temperature

where b = 2.8977719 mm K
