### FAQ

What is Interference of waves of two intensities ?
Interference of waves of two intensities is the superposition of two light travelling in almost the same direction result in a modification in the distribution of intensity of light in the region of superposition and is represented as I=I1+I2+(2*sqrt(I1*I2)*cos(Φ)) or Resultant Intensity=Intensity 1+Intensity 2+(2*sqrt(Intensity 1*Intensity 2)*cos(Phase Difference)). Phase Difference is used to describe the difference in degrees or radians when two or more alternating quantities reach their maximum or zero values, Intensity 1 is the quantity of energy the wave conveys per unit time across a surface of unit area, and it is also equivalent to the energy density multiplied by the wave speed and Intensity 2 is the quantity of energy the wave conveys per unit time across a surface of unit area, and it is also equivalent to the energy density multiplied by the wave speed.
