electromagnetic wave theory class 11 chemistry

In 1864, James Clark Maxwell established the wave nature of electromagnetic radiation. According to this theory, there are several points about radiation emitted from a substance. Class 11 Chemistry Planck’s quantum theory. Electromagnetic radiation is radiant energy that includes radio waves, microwaves, visible light, x-rays, and gamma rays, which differ in their frequencies and wavelengths. NCERT Exemplar Class 11 Chemistry is very important resource for students preparing for XI Board Examination. As shown in Figure 1.1.4 and Table 1.1.1 , the wavelengths of familiar electromagnetic radiation range from 101 m for radio waves to 10−12 m for gamma rays, which are emitted by nuclear reactions. Velocity of electromagnetic waves in a medium depends on the electric and magnetic properties of the medium. Waves have characteristic properties (Figure 1.1.2). Planck’s Quantum Theory- Lectures by Walter Lewin. Notes for Wave Motion chapter of class 11 physics. (Figure 1.1.3). The frequency (ν), the number of oscillations (i.e., of a wave) that pass a particular point in a given period of time. Substitute the value for the speed of light in meters per second into Equation 1.1.2 to calculate the wavelength in meters. A wave is a periodic oscillation that transmits energy through space. And hearing, seeing, tasting, and touching all involve intricate series of chemical reactions and interactions in your body. With such an enormous range of topics, it is essential to know about chemistry at some level to understand the world around us. The distance traveled by a wave per unit time is its speed (v), the distance traveled by a wave per unit time, which is typically measured in meters per second (m/s). Waves on strings, surface water waves and electromagnetic waves are transverse waves. These radiations consist of electric and magnetic field acting perpendicular to the direction of propagation of wave. Get CBSE Class 11 Chemistry chapter notes on ‘Structure of Atom’and learn about Atom, different atomic models, electromagnetic radiations, etc. It is given as: \(\vec{E}\times \vec{B}\). Introduction, Displacement current 03/12. Missed the LibreFest? Hence they can be polarized. The ripples on a pond, the sound we […] The document Wave Nature of Electromagnetic Radiation, Absorption Class 11 Notes | EduRev is a part of the JEE Course Chemistry Class 11. • Electromagnetic Wave:-The variation of electric and magnetic fields, perpendicular to each other, producing electromagnetic disturbance in space at right angles to each other, which have properties of waves and propagate through free space without any materialistic medium is called electromagnetic wave. Free Class 11 Science, Chemistry Notes, Class 11 Scince Syllabus, CBSE Class Notes and Study Material, from the latest edition of CBSE (NCERT) books. \(\lambda\) is the lowercase Greek lambda, and \(\nu\) is the lowercase Greek nu. Wave theory says that light is an electromagnetic wave. Electromagnetic radiation is radiant energy that includes radio waves, microwaves, visible light, x-rays, and gamma rays, … The usual units are oscillations persecond (1/s = s−1), which in the SI system is called the hertz (Hz). Electromagnetic radiation consists of two perpendicular waves, one electric and one magnetic, propagating at the speed of light (c). The speed of light, or of electromagnetic waves in a material medium is given by; where μ is the permeability of the medium and ε its permittivity. A similar phenomenon creates a rainbow, where water droplets suspended in the air act as tiny prisms. Light waves are transverse, i.e. In a vacuum, all forms of electromagnetic radiation—whether microwaves, visible light, or gamma rays—travel at the speed of light (c), which is the speed with which all forms of electromagnetic radiation travel in a vacuum, a fundamental physical constant with a value of 2.99792458 × 108 m/s (which is about 3.00 ×108 m/s or 1.86 × 105 mi/s).
