The Green Revolution in India is credited to Dr. M.S. Swaminathan, known as the “Father of the Green Revolution in India.” His efforts in introducing high-yielding variety (HYV) seeds, modern farming techniques, and scientific agricultural practices helped India achieve food self-sufficiency. Other key contributors include Norman Borlaug, who developed HYV wheat, Lal Bahadur Shastri, who … Read more
In India, ‘Green Revolution’ is Known to Credit to Whom? The Green Revolution in India is credited to Dr. M.S. Swaminathan, who is widely regarded as the “Father of the Green Revolution in India.” His contributions in introducing high-yielding variety (HYV) seeds, improving agricultural techniques, and promoting scientific farming methods helped India achieve self-sufficiency in … Read more
Principle of Conservation of Charge The principle of conservation of charge states that the total electric charge in an isolated system remains constant. Charge can neither be created nor destroyed, but it can be transferred from one body to another. Mathematical Expression: If q1,q2,q3,…q_1, q_2, q_3, \dots are the charges of different bodies in a … Read more
The relationship between electric field intensity (E) and potential gradient is: E=−dVdxE = -\frac{dV}{dx} Quick Explanation: Electric Field (E): Force per unit charge; its unit is V/m or N/C. Potential Gradient (dVdx\frac{dV}{dx}): Rate of change of potential with distance. Negative Sign (-): Indicates that the electric field points in the direction of decreasing potential. Key … Read more
The relationship between electric field intensity (E) and potential gradient is given by: E=−dVdxE = -\frac{dV}{dx} Explanation: Electric Field (E): It represents the force experienced by a unit positive charge in an electric field. Its unit is N/C or V/m. Potential Gradient (dVdx\frac{dV}{dx}): It refers to the rate of change of electric potential (V) with … Read more
Inertia of rest is the tendency of an object to remain at rest unless acted upon by an external force. It is a fundamental concept of Newton’s First Law of Motion, which states that an object will not change its state of motion unless an external force is applied. Examples of Inertia of Rest: Dust … Read more
Here are 5 more simple examples of refraction in daily life: Water in a Glass Looks Shallower – When you look at a glass of water, the bottom appears higher than it actually is because light bends as it moves from water to air. Sky Looks Blue and Sunsets Are Red – The sky appears … Read more
Here are 5 more examples of refraction in daily life: Light Bending in a Glass of Water – A spoon inside a glass of water appears bent or displaced due to refraction. Objects Seen Through a Glass Block Appear Shifted – When you look at an object through a thick glass slab, it appears displaced … Read more
Here are 10 daily life examples of refraction in short: Bent Pencil in Water – A pencil appears bent at the water surface due to light bending. Disjointed Straw in Water – A straw in a glass looks broken because of refraction. Mirage on Hot Roads – Light bends due to temperature differences, creating water … Read more
Refraction is the bending of light as it passes from one medium to another due to a change in speed. This phenomenon is commonly observed in our daily lives. Here are some real-life examples of refraction: 1. A Pencil Appears Bent in Water When a pencil is partially submerged in water, it appears bent at … Read more
