Statement B: Frequency of emitted radiation from a black body goes from a lower wavelength of higher wavelength as the temperature increases.
This statement is false. According to Wien's displacement law, the wavelength at which the intensity of radiation emitted by a black body is maximum is inversely proportional to the temperature. Mathematically, it can be stated as λmax ∝ 1/T, where λmax is the wavelength of maximum intensity and T is the temperature. So, as the temperature increases, the wavelength of maximum intensity decreases, which means the frequency of emitted radiation increases. Therefore, statement B is false.
Statement D: Rydberg constant has the unit of energy.
This statement is false. The Rydberg constant, denoted by R, is a fundamental constant in physics that appears in the equation used to describe the wavelengths of spectral lines emitted by hydrogen atoms. The value of the Rydberg constant is approximately 1.097 × 10^7 per meter. It is defined as the product of the speed of light, Planck's constant, and a numerical constant known as the Rydberg constant for hydrogen. The Rydberg constant has the unit of inverse meter (m^-1), not energy. Therefore, statement D is false.
In summary, the false statements are B and D. The frequency of emitted radiation from a black body increases with temperature, and the Rydberg constant has the unit of inverse meter (m^-1), not energy.
