Question

7. The According to Wien’s Law (λmax = 3×106/T), what is the temperature of the radiation? Recall that to use this formula, the wavelength must be in nanometers (1nm = 10−9 m) and the temperature will be in Kelvin.

Answer 1

According to Wien’s Law:

`\lambda_(peak) = (2.9 * 10^(6) )/(T(K))`

where;

`\lambda_(peak)` is the wavelength

T(K) is the temperature in Kelvin

Putting the values given in the above equation:

`{T(K)} = (2.9 * 10^(6) )/(\lambda_(peak))`

`{T(K)} = (2.9 * 10^(6) )/(3 * 10^(3))}`

T(K) = 0.966×
`10^(3)`
