engineering physics lab viva questions with answers

1. What is semi conductor diode laser?
Semiconductor diode laser is a specially fabricated pn junction diode. It emits laser light when it is
forward biased.

2. What is LASER?
The term LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a device
which produces a powerful, monochromatic collimated beam of light in which the waves are coherent.

3. What are the characteristic of laser radiation?
Laser radiations have high intensity, high coherence, high monochoromat ....etc

physics photo diode characteristics viva question with answers

This light detector is a current-to-voltage converter. The FET input op-amp prevents the loading of the photodiode and the voltage at the output is proportional to the current in the photodiode. So long as the photodiode response to the light is linear, the output voltage is proportional to the light falling on the photodiode. ....etc

It is impossible to do an experimental measurement with perfect accuracy. There is
always an uncertainty associated with any measured quantity in an experiment even
in the most carefully done experiment and despite using the most sophisticated
instruments. This uncertainty in the measured value is known as the error in that
particular measured quantity. There is no way by which one can measure a quantity
with one hundred percent accuracy. In presenting experimental results it is very
important to objectively estimate the error in the meas ....etc

Examiner (E): What was the experiment allotted to you?

Students(S): Sir, I was assigned the experiment to determine the internal resistance of a primary cell using potentiometer.
E: OK, Tell me the principle of a potentiometer

S: Sir. The principle of a potentiometer is that the potential drop across any length of a wire of uniform cross section and composition and carrying a constant current is directly proportional to the length.
E: Good. What is internal resistance?

S: The resistance offered by the electrodes and electrolyte of a ....etc
