A common radio wavelength observed coming from astronomical objects is 21 cm. What temperature is associated with this radiation
qaws [65]

Answer:

The temperature associated with this radiation is 0.014K.

Explanation:

If we assume that the astronomical object behaves as a black body, the relation between its <em>wavelength</em> and <em>temperature</em> is given by Wien's displacement law.

\lambda_{max}=\frac{b}{T}

where,

λmax is the wavelength at the peak of emission

b is Wien's displacement constant (2.89×10⁻³ m⋅K)

T is the absolute temperature

For a wavelength of 21 cm,

T=\frac{b}{\lambda _{max} } = \frac{2.89 \times 10^{-3} m.K  }{0.21m} =0.014K

Bad White [126]
Soil profile
Soil profile is the vertical sequence of the layers of soil. Furthermore, there are actually six layers of the soil which involves the organic matter, -where most humus is present-, surface soil, the subsoil, the parent rock, and the bedrock as the innermost and core layer of the soil. In addition each soil layer has three to four soil horizon. These horizons are the physical features of the soil, mainly the texture, color and composition.
