The concept of Phase and Waveforms

A wave is a vibrational phenomenon that serves as a medium for energy transfer and exists in various forms, such as sound waves, radio waves, and light waves. A wave has several different properties, including period, amplitude, frequency, and speed.
Phase is a concept that explains where a wave is located within its cycle. When there are two waves, it represents how far apart they are in time, or in other words, the difference in their temporal positions. Phase is expressed in degrees, dividing one cycle into 360 degrees.
