  2. In Young’s double-slit experiment, fringe width (w) is directly proportional to the distance (D) between the slits and the screen, given by w = λD/d . When D is doubled, the fringe width also doubles. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-11/

  3. The work function of a metallic surface is the minimum energy required to eject an electron from the metal's surface. It depends on the material and is typically measured in electron volts (eV). For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-11/

  4. Metal B has a lower threshold wavelength because threshold wavelength (λ th ) is inversely proportional to the work function (W) as λ th = hc/W . A higher work function results in a shorter threshold wavelength. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapRead more

  5. The phenomenon that demonstrates the quantum nature of electromagnetic radiation is the photoelectric effect, where light ejects electrons from a material, showing light's particle-like behavior as discrete photons.
