What are the characteristics of laser?
Characteristics of LASER:
The given are the properties of laser that differentiate this from ordinary light as:
a. Monochromaticity
b. Directionality
c. Coherence
d. Intensity
Graphs of current against voltage for two resistors P and Q are shown in Figure. Determine the value of every resistor.
If a ring were constructed as knid of a space station. How fast must a 50.0-m-radius ring rotate to simulate Earth's gravity?
how do we see light?
What are different pumping mechanisms in LASERS?
An aereplane has velocity 500m/s with respect to air. Wind blows with velocity 20m/s along north. Then in what direction pilot should be heading so as to go along North-east direct
Newton's Law of Gravitation In 1687, Newton did not "discover" gravity but he did figure out that gravity is universal. It makes a ball fall when you drop it on earth. It also
