What Are the Wavelength and the Corresponding Photon Energy (In $( c =$

question 168

Short Answer

What are the wavelength and the corresponding photon energy (in electron-volts) of the primary light emitted by an ideal blackbody at each of the following temperatures? $( c =$ $3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } , 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J}$ , and the constant in Wein's law is $0.00290 \mathrm {~m} \cdot \mathrm { K }$ )
(a) $400 ^ { \circ } \mathrm { C }$ ?
(b) $800 ^ { \circ } \mathrm { C }$ ?
(c) $1200 ^ { \circ } \mathrm { C }$ ?
