What factors affect the de Broglie wavelength of a particle?
What factors affect the de Broglie wavelength of a particle?
The de Broglie wavelength depends on:
Planck's constant h (a universal constant),
velocity v of the particle
mass m of the particle.
Upvote Why regardless of the intensity of light, the photoelectric emission not occur below the threshold frequency?
Why regardless of the intensity of light, the photoelectric emission not occur below the threshold frequency?
Photons do not have enough energy ( )to overcome the work function (? ) of the material below the threshold frequency.The energy per photon remains too low to liberate electrons even if the light intensity is increased, so photoelectric emission cannot occur.
Upvote In modern physics, what is the significance of de Broglie’s hypothesis?
In modern physics, what is the significance of de Broglie’s hypothesis?
According to de Broglie's hypothesis, all matter exhibits wave-like behavior. It laid the foundation for quantum mechanics by introducing the concept of matter waves. The dual nature of particles (both wave and particle) is essential in designing technologies like electron microscopes and helps expl

How does the Shiksha's NCERT Exemplar help in mastering Chapter 12 – Atoms?
The NCERT Exemplar given on Shiksha's website provides a variety of numerical, conceptual and application-based questions around energy transitions, atomic models, and spectral series. It is a powerful study material for CBSE Board examination preparation and competitive exams like NEET and JEE.
Upvote According to Bohr’s theory, why do electrons not fall into the nucleus?
According to Bohr’s theory, why do electrons not fall into the nucleus?
According to Bohr's postulates, in specific stable orbits, electrons revolve without emitting energy. Energy is only absorbed or emitted when electrons jump between these orbits, preventing them from spiraling into the nucleus.
Upvote In understanding atomic structure, what is the significance of Bohr’s model?
In understanding atomic structure, what is the significance of Bohr’s model?
The concept of quantized energy levels for electrons in atoms is introduced by Bohr's model. Although, Bohr's model could not explain the spectra of multi-electron atoms. It helped lay the foundation for quantum mechanics and successfully explained the spectral lines of hydrogen.
