The superposition of two periodic oscillations with frequency f1 and f

1.	The superposition of two periodic oscillations with frequency f1 and f2 is a) is always periodic b) always aperiodic c) periodic if (f1 / f2) is a rational number d) periodic if (f1 / f2) is an irrantional number
Answer» xed interval of TIME is known as time period of the periodic motion. Examples of periodic motion are motion of HANDS of the CLOCK, motion of PLANETS around the sun etc. Oscillatory motion is defined as the to and fro motion of the body about its fixed POSITION. Oscillatory motion is a type of periodic motion.
