When it comes to mathematics, skipping any chapter is never advised. However, you can make sure your child studies regularly to avoid any issues. Some tips will make studies for exams easier, read ahead to know more.

How To Study From Maths NCERT Books?

Using NCERT books is very helpful because;

• The language used in the book is very simple, meaning, your child can read it himself.
• Reputed experts and teachers with vast experience have written the books.
• NCERT books are a genuine source of information.
• NCERT books are great for understanding the concepts easily.

Start Chapter-Wise

One of the best ways to make use of NCERT books is to study them chapter-wise. It means, your child studies the chapter in the textbook once and then do the exercises and then move on to the NCERT books. This will ensure your child is completely prepared for the exams. It is important to give equal time to both books to ensure your child is completely prepared. Solving all the problems present in the book means more practice and more knowledge.

Make A Study Schedule

A study schedule is very important when it comes to studying for the exam. Now, you can make separate study schedules for your child- one for the textbook and the other for the NCERT book. Or you can have one study schedule including both. Don’t overburden your child, but make sure you cover all the chapters from both books. When it comes to Mathematics, practice makes perfect.

Focus on Challenging Chapters

Your child needs to concentrate more on difficult topics, but without taking too much time. Maths is a subject where your child can score full marks. Therefore, make sure all chapters are covered.

Sample Question Papers

Solving sample papers is another great way to make sure your child is thorough. It can also help you understand their strengths and weaknesses, and since you will have ample time before the exams, you can work on any weaknesses.

Always Clear The Doubts

If your child has any doubts regarding a concept, make sure it gets cleared immediately. You can either talk to the teacher or hire an online tutor. It is also possible to understand the concept clearly with the help of the NCERT books.

Finally, remember, make sure your child remains calm and panic-free before and during the exam as it will help him remember everything more clearly. Also, try to make learning more fun, with quizzes, interactive games, and more as this will help your child learn better.

Spectroscopy involves the investigation and measurement of spectra produced due to matter interacting to give off electromagnetic radiation. In other words, it refers to the dispersion of light into component colours. It involves the interactions between molecules and electromagnetic radiation. Therefore that tells you that molecules oscillate from a lower energy level to a higher energy one and back repeatedly. In the process, the molecules absorb and radiate electromagnetic radiation. Here includes everything you need to learn about Molecular Spectroscopy.

Understand the meaning of a Molecule

A molecule is a group of positively charged atoms surrounded by a considerable number of negatively charged electrons. That explains molecular stability since there is a balance between the attractive and repulsive forces of the negatively charged electrons and positively charged nuclei. Moreover, a molecule is also characterized by the resulting energy that emerges from these interacting forces.

Types of Molecular Spectroscopy

The electromagnetic spectrum of a series of wavelengths is produced whenever a matter is exposed to any electromagnetic radiation. As a result, the Molecules will absorb a certain amount of wavelengths to the vibrational, higher electronic, and rotational energy levels. Therefore, the series of wavelengths a given molecule absorbs gives off a distinct molecular spectrum that lies in the specific region of the electromagnetic spectrum. Here are three types of molecular spectra you should know:

• Pure Rotational Spectra

Pure rotational spectra occur when a molecule absorbs the least amount of energy that compels it to transit from one rotational level to the next but within the same vibrational level. It is possible to observe rotational spectra using the spectral region of Far Infrared and Microwaves. Moreover, the energies in these types of spectral regions are very small. That’s why they are referred to as all rotational spectra, the microwave spectra.

• Vibrational Rotational Spectra

Vibrational, rotational spectra occurs when a molecule absorbs sufficient energy that causes the molecule to move from one vibrational level to the next within the same electronic level. However, in this case, both vibrational and rotational transition takes place. That is how you end up with vibrational, rotational spectra. With vibrational spectra, it is easy to observe the spectra in the Near-Infrared Spectral region. That’s called vibrational, rotational spectra, the Infrared spectra.

• Electronic Band Spectra

Lastly, electronic band spectra happen when the radiation’s exciting energy is large enough to aid the successful transition from one electronic level to the next. Both rotational and vibrational level changes accompany this transition. Additionally, a set of closely spaced lines appear for each vibrational transition. These closely spaced lines are known as bands Because the corresponding rotational level changes.

Molecular Spectroscopy primarily involves the excitation of atoms and molecules using photons. They are excited by either resonant vibrations or electronic transitions based on the induced quantum mechanical changes. While vibrational transitions correspond to changes made within the molecular vibrational states, they typically appear in the infrared region. On the other hand, Electronic transitions specifically correspond to changes in the electronic state of the molecules. Moreover, it often appears in the UV-visible region.
