The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the sc…

Suppose that y1(x,t) and y2(x,t) are two independent wave functions, which describe the displacements vertical (in meters) of a string, as a function of position x (in meters) and time t (in seconds): (See image) For what values of the phase constant ϕ1 does destructive interference occur? Compliment: According to an article I've read on the internet, destructive interference occurs when ϕ1-ϕ2=180° What I did was : ϕ1+(π/3)=π Is it wrong?

Derive the transmission and reflection coefficient of monochromatic plane wave propagating from non conducting incident to conducting incident. Assume that the incident wave hits perpendicular to the medium. Can you please help me with this problem show a complete and explicit solution with an explanation step by step. Note: No shortcuts and don't skip any mathematical algebra.

For the figures shown below, the two sources are 6cm apart, and they are in phase. Two paths are drawn from the sources to a point. (The picture is to scale, even if the sources are not 6cm apart on the paper.) (a) If the wavelength of the two sources is 2cm, for each picture, figure out whether the point marks a position of constructive or destructive interference. (b) Repeat if the wavelength is 1cm.
