A hydrogen atom is in the ground state. It absorbs energy and makes a transition to the n = 3excited state. The atom returns to the ground state by emitting two photons. What are their wavelengths? ? m (lowest energy photon) ? m (highest energy photon)
Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting
1) Consider 2kg mixture of H 2 and N 2 ideal gases inside a closed piston-cylinder device at 150kPa and 100o C. This mixture has 0.4 mole fraction of H 2 . This mixture undergoes
Majority and minority charge carriers A pure semiconductor has equal number of holes and electrons. But an extrinsic semiconductor has majority charge carriers. When a tri
Explain the applications of polarization of light? Write any four applications of interference of light. Illustrate how plane polarized light obtained by reflection.
UV radiations and X - rays are: UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1n
DERIVATION OF ANGLE OF DEVITAION
Consider a current loop where the circulating current is I. This may be for an example of a coil carrying a current. We will assume that the current loop lies within a single plane
How to determine the co efficient of viscosity of liquid by capillary flow method?
How are glass fiber ended? Glass fibers are, usually potted or encapsulated at the single end with the help of an epoxy compound or adhesive. It results on a very hard element
To determine the acceleration due to gravity using a simple pendulum. Apparatus: Pendulum, meter scale, stand, stop watch, vernier callipers. Procedure: 1. The diameter of the bob
