Q. Why does the sky appear blue in colour?
As-per to the Rayleigh's scattering law the shorter wavelengths are scattered much more than the longer wavelengths. The blue look of sky is due to scattering of sunlight by the atmosphere. Blue light is scattered to a bigger extent than red light.
This scattered radiation results the sky to appear blue.
An electron, an alpha-particle and a proton have the similar kinetic energy. Which one of these particles has the main de-Broglie wavelength?
It is desired to lessen the reflection of light by the outer surfaces of the objective lenses of a pair of binoculars. These surfaces are the foremost surfaces that light hits on e

DC voltage measurements: Examples of how to make DC voltage measurements are show in the two diagrams below. In both cases, the red and black test leads are connected to the '
QUESTION 1 A car of mass 800 kg is pulling a trailer of mass 300 kg up the slope of angle ? to the horizontal where sine ? = 1/200. Resistance to motion (apart from gravity) is 1.
Instantaneous velocity and speed are explained at a given or particular instant and are shown by ,
The Centralia power plant emits SO 2 at the rate of 150 g/s. It has an effective stack height of 50 m. Surface winds at 10 m are steady at 2.5 m/s and it is a fall afternoon. a
The recombination procedure is represented with returning the electron from the CB where it is free into a hole in the VB where it is in a bond. The excess energy of the electron
1. The probability of dissociation of water into H + and OH - , to a good approximation, can be characterized by the Boltzmann distribution: W ≈ e -Eα/ KT If, at 27°C, 1.
There are two major differences between "center of gravity" and "center of mass": 1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "cent
