Mahmud Ghaznavi invaded India The first major attack by the Turks came when Mahmud Ghaznavi of Ghazni kingdom called a Turk king attacked India. He did not want to rule in India. His eyes were on expanding his kingdom Ghazni by defeating other Ottoman kings in the region of Iran, Afghanistan and Khorasan.  I was engaged when Mahmud Ghaznavi did not want to rule in India, then why did he come to India because he was trying to raise money to build his army, in this effort he tried 17 times on various Rajput states from 1000 to 1025. Invaded He defeated many kings and captured their wealth, broke and looted those temples and Buddhist monasteries in which a lot of wealth was collected.In this, the invasion of Somnath temple in 1025 AD is the most famous.

India at the time of Ottoman invasion There was no powerful ruler at the time of the advent of Islam in North India. In the early 11th century, India was divided into more than 100 small political units or states over which many small and big kings and feudatories ruled, mostly Rajputs in it. Therefore, this era has been called the Rajput era. The rulers of these small states got involved in expanding the state to fulfill their personal ambitions. As a result of this, political chaos increased further and in such a situation, the decline of central power was natural. The society was based on the bond of casteism and discrimination. At this time there was more rigidity in the caste system. Indian society considered its food and ethics best and so no attempt was made to become familiar with what is happening in other countries. Nor availed. Turk invasion of India In those days there were many big and small kings in India and in northern India there were Rajput animal kingdoms like Chauha...

Basics of Islam Religion: Islam is one of the major world religions, with over a billion followers globally. It is based on the teachings of the Prophet Muhammad, who is considered the last messenger of God (Allah in Arabic) by Muslims.  Here are some fundamental aspects of the Islam religion: 1. The Five Pillars of Islam: Islam is characterized by the Five Pillars, which are the foundational acts of worship and practice for Muslims: Shahada (Declaration of Faith): The basic creed of Islam, declaring the oneness of God and the prophethood of Muhammad.  Salah (Prayer): Muslims are required to pray five times a day facing the Kaaba in Mecca. These prayers are known as Salah or Salat. Zakat (Charity): Muslims are obligated to give a portion of their wealth to help those in need, typically 2.5% of their savings and investments. Sawm (Fasting during Ramadan): Muslims fast from dawn to sunset during the holy month of Ramadan. This includes abstaining from food, drink, and sinful b...

Law of light emission 1) The rate of emission of light electrons from the surface of a metal is proportional to the intensity of light falling on the surface of the metal. 2) The maximum speed energy of the emitting light electrons does not depend on the intensity of incident light. 3) The maximum speed energy of light electrons increases with the increase of incident light allocation. 4) If the frequency of incident light is less than a minimum allocation, no electrons are emitted from the surface of the metal. This minimum distribution is called the sill level. The value of the sill is different for different metals. 5) There is no time lag between light falling on the metal surface and electrons being emitted from the metal surface, ie electrons are emitted as soon as the light falls on the metal surface.

Why light is produced due to electric immersion in gases at low pressure? The electrons in the gases accelerate due to high volatility and when these electrons collide with an atom, they excite it when these excited atoms return to their normal state and emit light.

What is positive rays? How can positive rays be generated? Explain its usefulness and quality? Positive rays or canal rays Goldstein used the cathode with an aperture in the immersion while experimenting with cathode rays and kept the pressure of gas in this tube at 10 -2 mm , and when the high voltage was applied between the cathode and the anode, the back of the cathode started to glow . This radiance differs from the radiance emanating from cathode rays. Therefore, this brightness is due to any other type of rays because these rays pass through the porous cathode, so Goldstein studied these rays and said that these rays are made up of positively charged particles, hence they are called positive rays. Due to origin of Positive rays or canal rays When the rapidly moving electrons of the cathode rays emanating from the cathode collide with the atom or particle of the gas between the anode and the cathode, they ionize the atoms that are ionized, leaving a positive charge equal to the mi...

Illustrate JJ Thomson's method of finding the specific electric charge (E / M) of an electron? To find the ratio of charge and mass (e / m) of electron by J.J. Thomson J.J. Tamson used the fact that the electron beam can be projected by magnetic and electric fields to find the value of the specific charge (e/m) of an electron. Composition It has a long immersion tube of glass. At the left end of this tube, there is a porous anode attached to the cathode and some distance further away from the cathode, the vacuum is generated in the tube up to about 10 power minus 2 mm pressure. Inside the tube, there are two parallel plates of metal between which the electric potential constant is used uniformly in the paper floor at which place the magnetic field perpendicular to the bottom of the paper goes. At this place magnetic field is generated by placing an electromagnet perpendicular to the bottom of the paper outside the tube, zinc sulfide is coated on the wide part of the immersion ...
