State two conditions to obtain sustained interference of light
In Young's double slit experiment, using light of wavelength 400 nm, in terference fringes of width 'X' are obtained. The wavelength of light is enhanced to 600 nm and the separation among the slits is halved. If one wants the observed fringe width on the screen to be the same in the two cases, find the ratio of the distance among the screen and the plane of the interfering sources in the two arrangements.
Linear circuit :- It can be described as one, whose parameters are constant i.e. they do not change with voltage or current.
What is meant by the term 'modulation'? Define with the help of a block diagram, how the process of modulation is carried out in radio broadcasts.
Discharging: The cell is connected across some load during discharging. As the direction of current by the cell is reversed during discharging the negative ions go in the directio
Illustrate the source of stellar energy. Describe the carbon-nitrogen cycle and proton - proton cycle occurring in stars. Write down a note on ‘Breeder reactor'.
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
Q. What do you mean by Ant reflecting Films? When a beam of light travels normally from a medium of refractive index µ 2 to a medium of refractive index µ 1 , a part of light
Null experiment: An experiment that yields no result after being executed. Null experiments are just as meaningful as non-null experiments; if current theory determined an obs
