Quantum Theory of Light:
Wave theory failed to describe some new effects in 19th century. A German Physicist Max Plank gave theory about the nature of light.
1. Light is emitted from a source in tiny packets of energy or Quanta.
2. These energy packets or bundles of light known as Photon.
3.The light is emitted and absorbed in the form of Photons.
4.The energy possessed by a photon depends upon its frequency
What makes a good illuminator? Illuminators should perform three separate tasks along with a degree of efficiency. Initially must house a lamp and its transformer, power sourc
A ram-air intake is any intake design which uses the dynamic air pressure produced by vehicle motion to increase the static air pressure inside of the intake manifold on an engine,
Spectrum and electromagnetic radiations: What is a spectrum? Ans: A spectrum is a group of wave lengths or frequencies. What are the electromagnetic radiations? Ans:
A projectile is projected with speed u at an angle of 60 degrees with the horizontal from the foot of an inclined plane.If the projectile hits the plane horizontally,the range on t
Example of Ohm Law Now that we know how to draw a circuit, let's figure out what is happening in a simple one resistor, one battery (voltage source) circuit. Example 1 - H
NEGATIVE ACCELERATION OR RETARDATION OF DECLERATION: If velocity of a body is reducing, then its acceleration is said to be negative. The direction of negative acceleration is
the magnitude and direction of acceleration of body both are constant will the body moves in straight line
Resolution of Forces by Calculation: One vector was resolved into two mutually perpendicular components. So if there are several vectors each can be resolved into two
A 65g ball with a diameter of 3.1cm begins at rest and rolls down an incline. The angular acceleration of the ball is a constant 0.55rad/s2. ( I ball=(2/5)mr2 ) Calculate the net t
