According to de-Broglie theory, the wavelength of de-Broglie wave is given by
Where h = Plank's constant, m = Mass of the particle, v = Speed of the particle, E = Energy of the particle.
The smallest size of wavelength whose measurement is possible is that of gamma-rays.
The wavelength of matter waves associated with the microscopic particles like electron, proton, neutron, alpha-particle etc. is of the range of 10-10m.
Shell type transformers . In this type of transformer the iron core surrounds the copper windings. The core is in the shape of numeral 8. The entire flux passes by the central pa
Path of a projectile The apparatus below can be used to indicate the independence of the horizontal and vertical velocities of a projectile. The projectile is a metal ball, and
A reaction is first order in A and second order in B. (a) Write differential rate equation. (b) How is the rate affected if the concentration of B is tripled? (c) How is
Q. A transistor is connected in CE configuration. The voltage drop across the load resistance ( Rc) 3 k is 6 V. Find the base current. The current gain α of the transistor is 0.97.
Understand the manufacturing technique of optical fibres by using chemical vapour deposition method. A Traversing oxy-hydrogen flame heats the reaction zone to a temperature ar
Chemical changes during: Discharging: The current will flow from positive to negative plate in the external circuit. As current now enters by negative plate, the negative
If the electrons striking the target eject an electron from the K-shell of the atom, a vacancy is crated in the K-shell. Instantly an electron from one of the outer most shell, say
A conductor moves with a velocity of 20m/s at an angle of (a) 90 ? (b) 45 ? (c) 30 ? , to a magnetic field produced among two square-faced poles of side length 2.5cm. If the
