NCERT textbook controversies. The National Council of Educational Research and Training (NCERT) is an apex resource organisation set up by the Government of India to assist and advise the central and state governments on academic matters related to school education. The model textbooks published by the council for adoption by school systems ...
Arikamedu is a coastal fishing village, under the Ariankuppam Panchayat, on the southeastern coast of India, 4 kilometres (2.5 mi) from Pondicherry, on the Pondicherry-Cuddalore road; it was originally a French colonial town. It is located on the bank of the Ariyankuppam River (for most part of the year the river is considered a lagoon), also ...
He used carefully calibrated tuning forks to monitor the rotation rate of the air-turbine-powered mirror R, and he would typically measure displacements of the slit image on the order of 115 mm. [7] His 1879 figure for the speed of light, 299944±51 km/s, was within about 0.05% of the modern value.
The same discrepancy applies to all illuminants in the D series—D 50, D 55, D 65, D 75 —and can be "rectified" by multiplying the nominal color temperature by ; for example … = for D 65. To determine the D-series SPD (S D ) that corresponds to those coordinates, the coefficients M 1 and M 2 of the characteristic vectors S 1 and S 2 are ...
Luminous intensity. In photometry, luminous intensity is a measure of the wavelength -weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.
v. t. e. Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the ...

For example, for visible light, the refractive index of glass is typically around 1.5, meaning that light in glass travels at c / 1.5 ≈ 200 000 km/s (124 000 mi/s); the refractive index of air for visible light is about 1.0003, so the speed of light in air is about 90 km/s (56 mi/s) slower than c.
