Explain about the monochromaticity of laser.
Monochromaticity:
The light emitted through a laser is monochromatic, that is this is of one wavelength (colour). Although in case of ordinary light, several wavelengths of light are emitted. It is the properties of laser, which differentiate this from ordinary light.
Nichrome: Nichrome is an alloy of Manganese 1.5%, nickel 75% to 78%, chromium 20% to 23% and a little percentage of iron. Properties: 1. Its elec trical resistivity
Inertia: the resistance an object has to a alter in its state of motion. Newton's first law of motion declares that force is NOT required to keep an object in motion. Slide
A particle with mass m = 2:5 is moving along a straight trajectory. The distance covered by a particle is described by the function S(t) = t 3 + 2t 2 , where t > 0 is the time
What is electricity
Characteristics of resistances connected in parallel
What is the difference between unit cell and primitive cell In primitive cell, number of atoms per unit cell is one while if number of atoms per unit cell is greater than one i
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
What are the limitations of transmission electron microscope? Limitations of transmission electron microscope: a. In TEM, the materials need extensive sample preparation; we
Q. Define Specific Gravity? Answer:- Specific Gravity SG is a unit fewer quantities that gives the scientist or engineers an idea of how dense a substance is compared to w
Q. Illustrate how do you convert from Pascal to torr? Answer:- Converting the Pascal to the torr The pascal is a slighter unit of pressure than the torr and there are 1
