When two rays of same frequency, similar wavelength, and similar speed moves in the same direction, their superimposition gives result in the interference. Due to interference the last intensity of sound at that position is dissimilar from the addition of intensities due to every wave separately. This change of intensity due to superposition of two or more rays is called as interference.
The frequency of a wave is 50 Hertz and its wavelength is 25 meters. What is the velocity of this wave? Ans: The velocity of given wave is 1250 meters/second.
Besides solid, liquid, and gas, what is the fourth form of matter? Ans: The fourth form of matter is plasma.
Why different colours of white light travell with different speed in a glass prism,while they travell with same speed in air? Ans)Since in diffeernt medium frequecy remains const
It describes that the total energy (pressure energy, potential energy and kinetic energy) of an incompressible and non-viscous fluid in steady flow by a pipe remains constant throu
if CPH has mass, so CPH Theory is able explain the universe future. Universe should collapse. And it is able explain dark matter too. Am I wrong? Answer; you are correct that C
what is majority and minority charge carrier ?
A ray of light itinerant in air passes through a flat plate of glass. Refraction takes place. Where the refraction does occurs? Ans: Refraction takes places when light tra
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
