DAVISSON AND GERMER S EXPERIMENTS



In the year 1927 Davisson and Germer working in the Bell telephone laboratories of USA ,accidentally stumbled upon an experiment in which they observed diffraction of electrons in a crystal of nickel the way X-ray diffraction occurs in a crystal. When they calculated the wavelength that should be attributed to the incident beam on the basis of Bragg s law, the value matched exactly with the value of the wavelength evaluated by using de-broglie equatio ....etc

Materials Required: A Resistance wire, voltmeter, ammeter, battery, rheostat, meter scale, one way key, connecting wires etc.

Theory: If I be the current flowing through a conductor & V be the potential difference across its ends, then according to Ohm s law
V I
or V = RI
Where, R is the constant of proportionality. It is known as resistance of the conductor.
V/I=R
R depends upon the nature of material, temperature & dimensions of the conductor.

Procedure:
1. Clean the ends of the connecting wires with the help of sand p ....etc

Abstract Radio Frequency Identification (RFID) has been developed as an important technique for many high security and high integrity settings. In this paper, we study survivability issues for RFID. We first present an RFID survivability experiment to define a foundation to measure the degree of survivability of an RFID system under varying attacks. Then we model a series of malicious scenarios using stochastic process algebras and study the different effects of those attacks on the ability of the RFID system to provide critical services even ....etc

Noise Pollution

Most of us are very used to the sounds we hear in everyday life. Loud music, the television, people talking on their phone, the traffic and even pets barking in the middle of the night. All of these have become a part of the urban culture and rarely disturb us. However, when the sound of the television keeps you from sleeping all night or the traffic starts to give you a headache, it stops becoming just noise and start turning into noise pollution. For many of us, the concept of pollution is limited to nature and resources. H ....etc

Biasing a diode means applying appropriate DC voltage to a diode. A forward biased diode conducts
easily whereas reverse biased diode practically conducts no current. It means that forward resistance of a
diode is quite small as compared with its reverse resistance.
Forward current is the current flowing through a forward biased diode. Every diode has a maximum
value of forward current, which it can safely carry. If this value is exceeded, the diode may be destroyed
due to excessive heat. Reverse current or leakage current is the current t ....etc
