What is the difference among Free Electron Theory and Band Theory of solids?
Free Electron Theory:
This theory says that, metals conduct electricity due to the presence of free electrons in it. The outermost shells of metal atoms will be loosely bound with their nucleus. So the electrons in it are free to move anywhere in the solid.
These electrons are known as free electrons and these electrons are responsible for the conduction of electricity.
Lyman series: The series which define the emission spectrum of hydrogen while electrons are jumping to the ground state. All lines are in the ultraviolet.
Fun with a pendulum Suspend a hard ball about 8 cm in diameter on a cord over a table. The cord should be at least 1.5 m in length and should be just high sufficient off the ta
Hard Ferromagnetic Substances: Those substances that do not lose their magnetism or removing from magnetic field are known as hard magnetic substance such as steel.

Q. It is possible to have motion in the absence of a force. Yes it is True, in the absence of a force a body will continue moving in a straight line and at a constant velocity
after 1sec of projectile makes an angle of 45 with the horizontal after another 1 sec travelling horizontally find magnitude of initial velocity and angle of projection
Is there a way that you can gain potential energy and release kentic energy in Volleyball?
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
types of ANDGATE circuit and gate operation
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
