After her graduation in 2007, she met Byju Raveendran, [8] her instructor for GRE preparation. [3] [9] Byju encouraged her to become a teacher due to her questions during breaks between the classes. [3] Her career as a teacher began in 2008 [3] at age 21. [10] [7] In 2020, she told Fortune India, "It was an auditorium-style class with 100 ...
The Future School aims to cross the bridge from passive to active learning with an interactive learning platform blended with coding and other subjects like Math, Science, English, Music and Fine arts through storytelling. Byju's will launch the Future School in the United States, United Kingdom, Australia, Brazil, Indonesia and Mexico in May. [47]
Photoexcitation is the first step in a photochemical process where the reactant is elevated to a state of higher energy, an excited state.The first law of photochemistry, known as the Grotthuss–Draper law (for chemists Theodor Grotthuss and John W. Draper), states that light must be absorbed by a chemical substance in order for a photochemical reaction to take place.
The Indigo revolt (or Nil bidroha; Bengali: নীল বিদ্রোহ) was a peasant movement and subsequent uprising of indigo farmers against the indigo planters, that arose in Bengal in 1859, and continued for over a year.
He was the greatest scientist of modern India and one of the greatest intellects our country has produced in its long history. His mind was like the diamond, which he studied and explained. His life's work consisted in throwing light upon the nature of lights, and the world honoured him in many ways for the new knowledge which he won for science.
The light wave polarization specifies the form and location of the electric field vector's direction at a particular point in space as a function of time (in the plane perpendicular to the propagation direction). There are three possible polarization states for light, depending on where the vector's direction is located.

1962 Nick Holonyak Jr. develops the first practical visible-spectrum (red) light-emitting diode. 1963 Kurt Schmidt invents the first high pressure sodium-vapor lamp. [18] 1972 M. George Craford invents the first yellow light-emitting diode. 1972 Herbert Paul Maruska and Jacques Pankove create the first violet light-emitting diode.
