Class 12 is an essential milestone in your life as you take any serious decisions about your future study on your performance. Whether you select to be a doctor or engineer, you will have to deal with Physics Part II in every area. Making the concepts of class 12 concrete can immensely help you in obtaining good marks in the CBSE Class 12 board examination as well as in different competitive exams. First, you should imprint this in your mind that NCERT books are the most important tool that you can have to get well-versed with the basics.

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. Here electrons are emitted from the metal surface with the help of thermal energy.

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?

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.

NCERT Solutions for Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter

All these solutions help students of class 12 in attempting numerical problems and theory questions on the board and entrance exams. Subject experts have given all these solutions with a straightforward and detailed description. Question 1. Find the a maximum frequency, and b minimum wavelength of X-rays produced by 30 kV electrons.

In the experiment the intensity of electron beam is … Spectrum due to the emission of white light by gas at high temperature is known as an emission spectrum. De Broglie equation relate the particle character with the wave character of matter. An electron and alpha particle have the same de-Broglie wavelength associated with them. While photoelectric effect and Compton effect involve energy and momentum transfer, radiation behaves as if it is made of a bunch of particles-photons show particle nature of a wave. Electromagnetic Radiation is basically light, which is present in a rainbow or a double rainbow. Hence, we assume the dual nature of light. De Broglie waves Matter waves Radiation has dual nature, wave, and particle.

Hence, the maximum frequency of X-rays produced is. The work function of caesium metal is 2. What is the. Work function of caesium metal,. Frequency of light,. The photoelectric cut-off voltage in a certain experiment is 1.


Dual Nature of Radiation and Matter. (a) no electrons will be emitted as only photons can emit electrons. (b) electrons can be emitted but all with an energy.

What happens if the laser is brought nearer and placed 50 cm away. Why photo-electrons ejected from a metal surface have different kinetic energies although the frequency of incident photons are same? Define distance of the closest approach. What will be the distance of closest approach for an alpha-particle of double the kinetic energy? If the total number of neutrons and protons in a nuclear reaction is conserved how then is the energy absorbed or evolved in the reaction? Particle of mass M at rest decays into two particles of masses m1 and m2 having velocities V1 and V2 respectively. Find the ratio of de-Broglie Wavelengths of the two particles.

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.
