MCQs with answers on Wien displacement law  Introduction Wien displacement law is a mathematical approach to measure the highest wavelength of blackbody emission with maximum intensity at a fixed temperature of T. It clarifies the peak wavelength movement to shorter wavelengths at higher temperatures of heated objects. The law especially held good at shorter wavelengths of radiation emissions. And it failed to measure the peak wavelength positions of blackbody curves at higher wavelengths in constant temperature conditions. It plays a significant role in the color identification of thermal objects. This blog post not only discusses MCQs with answers on Wien displacement law, but it also includes image-rich topic supplements such as an infographic & mind map of Wien displacement law.  Wilhelm Wein, in 1893, derived a formula to measure the highest spectral radiance of a blackbody as a function of its wavelength at a particular temperature and is renowned as Wien displ...

 MCQs with answers on Planck constant Introduction: Planck constant is a universal constant and is a physical quantity invented in 1900 by the physicist Max Planck, the creator of the particle nature of light. Before the quantum law, classical physics interpreted the wave character of light, which could not explain the interaction of light with matter. MCQs of Planck's constant Planck's quantum theory proposed the quantum nature of electromagnetic radiant energies. Besides, it was the basic theory of quantum mechanics and explained the energy existence as tiny erratic bundles. This blog discusses MCQs of Planck's constant with descriptive answer explanations. Table of contents: Introduction Define Planck’s constant Mind map of Planck’s constant Multiple choice questions and answers of Planck’s constant Planck’s constant and reduced Planck’s constant Match the following quiz Numerical problems on Planck’s constant Define Planck's constant Kirchhoff's im...
