Electromagnetic Induction — Physics STD 12 Science — Question

Answer the following question:
In what way is diffraction from each slit related to the interference pattern in a double-slit experiment?

When a semiconducting material is doped with an impurity, new acceptor levels are created. In a particular thermal collision, a valence electron receives an energy equal to 2kT and just reaches one of the acceptor levels. Assuming that the energy of the electron was at the top edge of the valence band and that the temperature T is equal to 300K, find the energy of the acceptor levels above the valence band.

A circular loop of radius 4.0cm is placed in a horizontal plane and carries an electric current of 5.0A in the clockwise direction as seen from above. Find the magnetic field:

1. At a point 3.0cm above the centre of the loop.
2. At a point 3.0cm below the centre of the loop.

Why are microwaves considered suitable for radar systems used in aircraft navigation?

How does produced magnetic field at any point depends on current flowing through a long and straight conductor?

When an electric dipole is kept perpendicular to an electric field, what will be its electric potential energy?

The I-V characteristics of a resistor are observed to deviate from a straight line for higher values of current as shown in the adjoining figure why?

Special devices, like the klystron valve or the magnetron valve, are used for production of electromagnetic waves. Name the waves and also write one of their applications.

If the rate of change of current 2 ampere/ second induces an emf of 40 mV in the solenoid, what is the self-inductance of this solenoid?
