Explain in one or two complete sentences what happens after two displacement waves pass through each other. remember to use proper grammar and mechanics when writing your sentences.

After two displacement waves pass through each other nothing happens, they can continue to travel in the directions they were initially traveling. When waves overlap that is when the interference is happening. During the interference of the waves, the resulting amplitude of the wave is simply the sum of amplitudes of the interfering waves. Wave interference is that the development that happens once 2 waves meet while traveling on an identical medium. The interference of waves causes the medium to require on a shape that results from the net impact of the 2 individual waves upon the particles of the medium.

Explanation:

physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed by either a numerical value, the product of a numerical value and a unit or a finite sequence of numerical values and units.
