NCERT Solutions for Class 10th Refraction of light through glass slab Refraction Through a Glass Slab Refraction Through a Glass Slab Introduction Refraction through a glass slab occurs when light passes from one medium to another and changes its direction twice: when entering and when leaving the slab. The glass slab is typically a rectangular … Read more
Refraction of Light and Its Important laws with Examples class 10th Science Notes Refraction of Light – Explanation and Laws Refraction of Light What is Refraction? Refraction is the bending of light as it passes from one medium to another. This change in direction happens because light travels at different speeds in different mediums. For … Read more
Concept of Shells and Subshells Concept of Shells and Subshells Introduction to Shells and Subshells In an atom, electrons are arranged in specific regions around the nucleus called shells. These shells, also referred to as energy levels, contain subshells, which further define the distribution of electrons. Shells are numbered as 1, 2, 3, and so … Read more
Bohr’s Atomic Model Bohr’s Atomic Model Introduction The Bohr model, proposed by Niels Bohr in 1913, introduced the idea that electrons travel in specific orbits around the atom’s nucleus. This model helped address some of the limitations of Rutherford’s model and incorporated early concepts of quantum mechanics. Although it has since been replaced by more … Read more
Rutherford Atomic Model Brief History In 1911, Ernest Rutherford, a New Zealand physicist, proposed the Rutherford model of the atom. He is renowned for his Gold Foil Experiment, which led to the discovery of the atomic nucleus. His model was a departure from J.J. Thomson’s “plum pudding” model and laid the groundwork for the modern … Read more
The Gold Foil Experiment, conducted by Ernest Rutherford in 1909, was a monumental experiment that transformed our understanding of atomic structure. It provided the first evidence of the existence of a dense, positively charged nucleus at the center of an atom, fundamentally changing the field of chemistry and physics. Historical Context Experimental Setup Expected Results … Read more

J.J. Thomson’s Atomic Model J.J. Thomson’s Atomic Model Introduction J.J. Thomson, a British physicist, proposed the first model of the atom in 1904, often referred to as the “plum pudding model.” His work marked a significant milestone in understanding atomic structure, moving beyond the notion of the atom as an indivisible entity. Historical Background Before … Read more
