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
Explain Newtons Third Law - Linear Motion Stating that a force is just a push or a pull is a bit of a simplification. If we exert a push or a pull on an object then the object
The power factor of an a.c. circuit is 0.5. What will be the phase difference among voltage and current in this circuit?
Yes magnetism more important for iit because the weight of this magnetism is very hign so be careful about this magnetism chapter All the best for your preparation
Frequency:- The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
Passing Lane velocity vs time graph Suppose the two cars below. The blue car begins ahead of" the red car. The red car actually begins off the screen.) Because the red car is
RANGE OF PROJECTILE: "It is the horizontal distance covered by the projectile from the point of projection to the point where it returns to its level of projection".
Wires A as well as wire B are both made out of copper. Both of wires have the same length. The diameter of wire B is doubles that of wire A. Answer: Resistivity is a charac
At what velocity a clock should move so that it seems slow by one minute in a day.
Take the difference among your experimental value and your known value, and divide that difference by your know value. Say you experimentally found the force of gravity to be 8m/s
Stokes' Formula: When a spherical object falls by the fluid, layer in immediate touch with it, sticks to it and goes along with the object with the same speed. The layer next to i
