If f1 and f2 are frequencies of two tuning forks, such that f1 < f2, then number of beats produced in one second are:
Correct answer: A. f2 - f1
- A. f2 - f1
- B. f2 x f1
- C. f1 - f2
- D. f2 + f1
Explanation
The beat frequency is the difference in frequency between two interacting waves. If you have two waves with frequencies f1 and f2, the beat frequency can be calculated using the formula:f= f1 - f2 This formula is commonly used in physics and signal processing when dealing with the interference or interaction of waves, such as in the case of two sound waves or two electromagnetic waves. The beat frequency represents the frequency at which the amplitude of the resulting wave (obtained by superimposing the two original waves) varies, creating a pulsating pattern..

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
