Summary of HC Verma Solutions Part 1 Chapter 22: Photometry
FAQs on HC Verma Solutions Class 11 Chapter 22 - Photometry
1. What is the role of a photon in photometry?
Photon is an elementary particle, which can be used to measure the intensity of light using the photoelectric effect. Photon exerts work when it absorbs an electron and ejects it. The number of ejected electrons shows the intensity of light which is measured in terms of the number of photons and not energy. Photons are a unit that is convenient to work with the energy of photons. HC Verma books help students to score more marks by providing various solved questions of different chapters. With the help of HC Verma's book, students get an idea about the exam pattern and how to attempt the exams. Students also get an insight into different topics of physics, which will help them in their future studies.
2. What is the importance of photometry?
Photometry has great importance in various fields of physics, astronomy, and technology. It helps in distinguishing between different luminous sources and also measures their intensities. Photometry is also used to calibrate the instruments used for measuring light. HC Verma books not only help students to score good marks in exams but also provide them with a basic understanding of the concepts of physics. With the help of the HC Verma book, students can develop a strong foundation in physics and also prepare themselves for competitive exams like JEE MAINS AND ADVANCEand other examinations.
3. What is the use of integrating spheres in photometry?
4. Explain the term thimble photometer?
The instrument consists of a thimble that has three equally spaced holes, known as an apothem. A photocell with a light detector is made to face these three holes for measurement of light intensity through these three holes respectively. The readings are then averaged to get the final value. HC Verma books not only help students to score good marks in exams but also provide them with a basic understanding of the concepts of physics. With the help of the HC Verma book, students can develop a strong foundation in physics and also prepare themselves for competitive exams, and definitely score well in them.
5. What is the term used for the ratio of electric power input to total power output in a photoelectric circuit?
The term used for the ratio of electric power input to total power output in a photoelectric circuit is called "efficiency." HC Verma books not only help students to score good marks but also provide them with a basic understanding of the concepts of physics. With the help of the HC Verma book, students can develop a strong foundation in physics and also prepare themselves for competitive exams like JEE MAINS, and ADVANCE and other examinations and Vedantu is a platform that helps students to score good marks in exams with the help of Vedantu students can learn physics in detail.
