The maximum energy in thermal radiation from a source occurs at the wavelength 4000 Å . The effective temperature of the source is (Wien's constant, b = 2.93 × 10 − 3 m K )

Question

The maximum energy in thermal radiation from a source occurs at the wavelength 4000 Å . The effective temperature of the source is (Wien's constant, b = 2.93 × 10 − 3 m K ), 7325 K, 8 00 K, 10 4 K, 10 6 K

MARKS App · Accepted Answer

According to Wien's displacement law λ m = b T ⇒ T = b λ m = 2.93 × 10 − 3 4000 × 10 − 10 = 7325 K
