Any kind of wave spreads out after passing through a small enough gap in a barrier. this phenomenon is known as any kind of wave spreads out after passing through a small enough gap in a barrier. this phenomenon is known as refraction antireflection diffraction double-slit interference

If a wave passes through a small gap, say a window, it spreads out such that it fills the space after the restricting barrier or the small gap. Such a phenomenon is referred to as diffraction.

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
