Describe about Helium-Neon Laser in short.
Helium-Neon Laser:
The first gas laser termed as Helium-Neon (He-Ne) laser (one of the illustrations for four level lasers) was constructed into 1961 year. The most general and inexpensive type of gas laser is generally constructed to operate into the red at 632.8 nm. Into this laser, the active medium is a mixture of He and Ne gas.
If a particle is projected vertically upward in a constant gravitational field with an initial speed v 0 . If there is a retarding force proportional to the square of the instantan
These capacitors are used as tuning capacitors in radio receivers. The two requirements of these capacitors are: (1) Frequency stability (2) Preventing micro
For an object moving in uniform circular motion, the direction of the instantaneous acceleration vector is: w) tangent to the path of motion x) equal to zero y)
A battery of emf 2v and internal resistance 0.1 ohm is being charged with a current of 5A. In what direction will the current will flow inside the battery? Ans) In charging cond
Q. How do you compute tensile strength? Answer:- Tensile strength is not actually calculated it's measured. It is classified as the point at which a sample of material fai
A ball with a mass of 25 grams is dropped from ledge 908 meters above the ground. What is its kinetic energy the instant before it hits the ground? What is the potential energy of
Q. If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction. It is not true, the object will accelerate only in the
a pendulum is timed ,first for 20 swings and then for 50 swings ; time for 20 swings = 17.4 sec and time for 50 sec = 43.2. calculate the average time per swing/
