Describe how tunneling takes place
When tunnel diode is forward biased, its initial behaviour is similar to that when it's reverse biased. Now, some of the filled energy levels on the n-side shift to a high energy level than empty level on p-side electron tunneling now occurs, from the n-side to the p-side. With the increase in forward bias, more and more electrons tunnel from N-side to the P-side.
Basic principles of spectrophotometry: An absorbance spectrophotometer is an instrument that measures the fraction of the incident light transmitted through a solution
Positive rays are sometimes called as the canal waves. These were found by Goldstein. If the cathode of a discharged tube has holes in it and the pressure of the gas is around 10-3
A ray of light is incident normally on an equilateral prism of refractive index 3/2 calculate devition. Ans) since the prism is equilateral therefore angle of prism is 60 0 =

Q. In Newton's ring experiment, the diameter of certain order of dark ring is measured to be double that of the second ring. What is the order of the ring? Data :
If a hydrogen atom in its ground state absorbs a photon with a wavelength of 93 nm, it jumps to an excited state. What is the value of the energy in that excited state?
how many seconds dose it take an elevator to travel 373m if it accelerates at 4.80 m/s^2 and has a velocity of 17.8m/s how much time does it take an elevator to travel 373 meters
Explain the Merits of Vacuum Diode over Semiconductor Diode (i) Vacuum Diodes can withstand high reverse voltages (ii) Vacuum Diodes can operate at fairly high temperature
FORCE: "Force is that agency which causes a body to alter its state of motion or rest". It is denoted by F ?
Consider an electron in a simple one-dimensional periodic potential. The energy of the electron will vary periodically due to the influence of the periodic potential, and can be de
