About Physics 11 Course Notes

You will learn many new ideas like electricity in physics class 11. The current flow in metals is based on free electrons. In the absence of an electromagnetic field applied to the outside (using a battery), the free electrons move randomly through the metal from one point to another and cause a zero net current .

When connected to a battery, free electrons accelerate due to the electric field generated by the battery and gain speed and energy. However, the passage is not smooth and the electrons collide with the crosslinked ions whose final gain (energy) is the ion. Since we know that body temperature is related to the vibrational energy of these ions, these collisions cause the temperature of the metal to increase. The energy loss of the colliding electrons and their acceleration by the electric field ultimately causes the electrons to drift in a certain direction. (Although the actual movement of the electrons is irregular, the general effect is that the electrons drift.) In addition to this mechanics, the most important part of class 11 physics is where you learn that movement means changing position over time. When a body is at rest, its position does not change over time. But how to describe the position of a body? To do this, we must describe it in relation to another body as a reference.

Rest and movement are therefore relative. A man seated in a car traveling on the highway at 55 km / h is resting relative to a traveling companion while moving relative to a person standing on the highway.

To describe rest and movement, we select a frame of reference, and then describe rest or movement relative to that frame of reference.

There are two types of movements: transnational and rotational.

If a body moves in such a way that it always remains parallel to it throughout the movement, it is translated. When a body moves so that each point on the body maintains a constant distance from a fixed axis in space, the movement is a rotation.

Introduction to Class 9 Biology

Biology (Gk. Bios-life and logos-to speech) is the branch of science that deals with the scientific study of life. It depends on other sciences (such as physics and chemistry) and has therefore become a multidisciplinary and multidimensional scientific branch. Biology is better known as "life sciences" because it seeks to understand how living things interact with other "living" and "non-living" things.

Precisely, biology is research, an ongoing investigation into the nature of life. Biology, being an important branch of science, requires a scientific approach to understand and obtain precise results.

• The term "biology" was coined by Lamarck and Treviranus in 1802.

• Aristotle is known as "father of biology and zoology".

• Theophrastus is known as the "father of botany".

• Microorganisms were first observed by A.V. Leeuwenhoek but Louis Pasteur is considered to be the father of microbiology.

• Emil von Behring (Germany) was the first Nobel Prize in physiology and medicine to receive this prize in 1901 for serum therapy against "diphtheria"

About the Physics 12 Course Notes

Class 12 physics subjects are interesting and require good learning materials to excel. Conceptual understanding can be improved by a digital solution. Optics is one of the most important chapters, and you will learn that nothing in its basic nature distinguishes light from any other electromagnetic wave. What distinguishes light from other electromagnetic waves is that we have receptors (eyes) that are only sensitive to electromagnetic radiation in a narrow range of wavelengths from about 400 nm (purple) to about 700 nm (red). We will treat light as a wave motion in the context of interference and diffraction, but as a flow of photons while explaining the photoelectric effect.

Huygens wave theory.

(i) Each point on a wavefront acts as a source of new interference and emits its own set of spherical waves called secondary wavelets. Secondary wavelets move at the speed of light in all directions as long as they move in the same medium.

(ii) The envelope or location of these forward wavelets indicates the position of the new wavefront at any later time.

(A surface where the wave disturbance is in the same phase at all points is called the wave front.)

The wave optics is an effect which depends on the wave nature of the light. In fact, interference and diffraction experiments prove that light (at least in these circumstances) behaves more like a wave than a flow of particles (as Newton believed).

Chapters of Physics class 12 Notes

Class 12 physics chapters are important for the CBSE board and for entrance exams like JEE and NEET. The weight of the chapters of class 12 in the selection test is greater compared to the chapters of class 11 of physics. Therefore, you must be more careful and prepare very well.
