VISUAL PHOTOMETRY: The branch of science which deals with measurement of brightness or luminous intensities of light emitted by different sources using certain standards and techniques is called visual photometry.
SOLID ANGLE : The ratio of the area of the surface of the portion of a sphere enclosed by the conical surface forming the angle to the square of the radius of the sphere is called solid angle.
LUMEN: Lumen is the amount of light energy emitted per second by a uniform (point) source of one candela with in a cone of unit solid angle.
CANDELA: Candela is defined as the luminous flux emitted per unit solid angle along normal to the surface by one sixtieth (1/60) square cm area of a black body radiator (source) kept at the temperature of solidifying platinum (at 2046 K).
Rayleigh criterion; resolving power: A criterion for finding out how finely a set of optics might be able to distinguish. It start with the supposition that central ring of on
a) Can a gravitational field be added vertorially to an electric field to get a total field? Describe it. b) Can two equipotential surfaces cut down each other? describe it.
In utilizing Kirchoff's Laws to analyze a circuit a student correctly calculates a negative value for one of the currents in the circuit. What does the negative sign signify?
Describe Kirchoff's Voltage Law? Ans. It describe, " the sum of the Voltage drops around a DC series circuit same to the applied voltage or source. E = E 1 + E 2 = E 3 .
Refracting telescopes, if uncorrected, suffer from chromatic aberration. Chromatic aberration occurs because: a) red light is focused more strongly than blue light b)
Explain vectors Vectors : a quantity that has a size as well as direction is known a vector. So, for example, the wind blows with some speed and in some direction. So the win
