Further, they are all designed with the latest academic year subject material so that any difference in the syllabus is accounted for as well. Together, students will be prepared to answer every type of question like subjective and objective and aim for the best in their last year of school. These main subjects can be very complicated for students and the revision notes for every chapter will allow them to have an expert studying pattern with which they can achieve so much better and also enjoy studying the subject. With the help of revision notes students can revise the syllabus in a concise manner. Short keynotes for Class 12 also contain colour diagrams. Because of colour diagrams, it becomes very simple to understand the concept applied while showing and explaining the topics. Our team is working continuously for the betterment of our students.

What is the a maximum kinetic energy of the emitted electrons, b Stopping potential, and c maximum speed of the emitted photoelectrons? What is the maximum kinetic energy of photoelectrons emitted? The power emitted is 9. Assume the beam to have uniform cross-section which is less than the target area , and c How fast does a hydrogen atom have to travel in order to have the same momentum as that of the photon? How many photons nearly per square metre are incident on the Earth per second?

Learning the important concepts is very important for every student to get better marks in examinations. The concepts should be clear which will help in faster learning. Ch : Dual Nature of Radiation and Matter. Cathode rays are the stream of negatively charged particles, electrons which are shot out at a high speed from the cathode of a discharge tube at pressure below 0. The minimum amount of energy required by an electron to just escape from the metal surface is known as work function of the metal.
