Assertion : For higher temperature, the peak emission wavelength of a black body shifts to lower wavelengths.
Reason : Peak emission wavelength of a black body is proportional to the fourth power of temperature.
To determine the correctness of the assertion and reason, let's analyze each statement individually.
Assertion: For higher temperature, the peak emission wavelength of a black body shifts to lower wavelengths.
This statement is correct. According to Wien's displacement law, the wavelength at which the peak emission of a black body occurs is inversely proportional to its temperature. As the temperature increases, the peak emission shifts towards shorter wavelengths, which are lower in value.
Reason: Peak emission wavelength of a black body is proportional to the fourth power of temperature.
This statement is false. The correct relationship between peak emission wavelength and temperature is given by Wien's displacement law, which states that the peak emission wavelength is inversely proportional to the temperature. It can be represented as λ_max ∝ 1/T, where λ_max is the peak emission wavelength and T is the temperature. There is no direct proportionality between the peak emission wavelength and the fourth power of temperature.
Therefore, the reason is false, as it does not provide a correct explanation for the assertion. However, the assertion itself is true, as supported by Wien's displacement law.
Hence, the correct answer is option C. The assertion is true, but the reason is false.
