5 days ago · Therefore, This is known as Wien’s displacement law. Here, λmaxis the wavelength at which Ebλ is the maximum at a particular temperature. The value of (Ebλ)max shifts towards the shorter wave lengths with increasing temperature. where the constant C3= 1.287 x 10–5W/m3K5. The maximum emissive power of a black body can be found from Planck ...
5 days ago · We can recall that the Wien’s displacement law gives us a relation between the peak wavelength in a blackbody spectrum and the temperature at which this peak occurs. It is essential to know that when temperature is increased, the wavelength at which the maximum Intensity is obtained becomes lesser than the value at lower temperature.
2 days ago · The Planck constant, or Planck's constant, denoted by , [1] is a fundamental physical constant [1] of foundational importance in quantum mechanics: a photon 's energy is equal to its frequency multiplied by the Planck constant, and the wavelength of a matter wave equals the Planck constant divided by the associated particle momentum.
4 days ago · Note: Before solving the problem, the student needs to be able to understand the different concepts of Radiation like Stefan’s law, Wien's Displacement law and the terms like total emissive power and spectral emissive power. A common mistake that students make while solving questions involving concepts of radiation is not being able to ...
2 days ago · Sirius is the brightest star in the night sky. Its name is derived from the Greek word Σείριος (Latin script: Seirios ), meaning lit. 'glowing' or 'scorching'. The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated α CMa or Alpha CMa. With a visual apparent magnitude of −1.46, Sirius is almost twice ...
