Question

If the maximum intensity of radiation for a black body is found at 2.65 what is temp of radiating body

Answer 1

Maximum intensity of radiation is wave length of the radiation = L = 2.65 micro meters

Wien's constant is given as = b = 2.9/10³ mK

The temperature of the body = T

The equation between maximum intensity and temperature is given by

LT = b   (that is wien's constant)

Substituting the values, we get

2.65 x T = 2.9/1000

T = 2.9 x 100000/(2.65 x 1000)

T = 1094K

Answer 2

Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body's temperature, called the Planck spectrum or Planck's law.
