For waves, it is more common to use radians (RAD) rather than degrees (DEG) when measuring angles. Radians are the preferred unit for measuring angles in mathematical calculations involving waves, as they simplify trigonometric functions and equations. Using radians also allows for more accurate and precise calculations when working with wave properties such as phase shifts, wavelengths, and frequencies. **

The main difference between rad and deg is the unit of measurement they represent. "Rad" stands for radians, which is a unit used to measure angles in the context of trigonometry and calculus. Radians are based on the radius of a circle and are used in advanced mathematics. "Deg" stands for degrees, which is a more common unit of measurement for angles in everyday use. Degrees are based on dividing a circle into 360 equal parts, with each part representing one degree. **
