Explain the Wave Particle Duality
Any object in the world can be considered to be a particle or wave and will exhibit properties of both. For example, a photon of light, an electron, and a moving baseball all have wave- and particle-like properties. Any object has an associated deBroglie wavelength, suggested by a young Ph.D. candidate, Louis deBroglie, in 1924. The deBroglie wavelength is given by
λ = h /mv where λ is the deBroglie wavelength in m, h is Planck's constant ( h = 6.626 x 10 -34 Js), m is mass of the object in kg, and v is its speed in m/s. We have dealt a bit with the wave nature of light in the last few chapters. As a particle, light comes only in discrete packages called photons. For a given frequency of light you cannot have less than one photon of energy.
E = h f or E = h (c/ λ) where E is the energy of a photon in joules, h is Planck's constant ( h = 6.626 x 10 -34 Js), f is the light's frequency in sec-1, c is the speed of light 2.99 x 108 m/s and λ is the wavelength in meters.
Because of concentration difference holes or electron try to vary from their side to other side. Only these holes or electrons cross the junction, having high kinetic energy. This
If a traveling wave is a sin or cos function of (x± vt) the wave than it is said to be harmonic or plane progressive wave.
Electric charge is a physical property of matter that causes it to experience a force when near other electrically charged matter. There exist two types of electric charges, called
Write a short note on different kinds of capacitors. Applying Gauss's law derive the mathematical expression for electric intensity due to a charged conducting spherical shall

Q. In Young's double slit experiment the distance between the slits is 1.9 mm. The distance between the slit and the screen is 1 m. If the bandwidth is 0.35 mm Compute the waveleng
Q. If a single force acts on an object, the object accelerates. yse it is definately true. Newton's second law.
Hertz; Hz (after H. Hertz, 1857-1894) The derived SI unit of frequency, explained as a frequency of 1 cycle per s; therefore it has units of s -1 .
Q. What are non-polar molecules? Give an example. i) A non-polar molecule is one in that the centre of gravity of the positive charges coincides with the centre of gravity of
