Question

Define and derive an expression for beat frequency

Answer 1

Answer:

Frequency means the number of vibrations performed by a particle during each second. formula is 1/t.

Answer 2

Frequency is the number of cycles in a unit of time. The "cycles" can be movements of anything with periodic motion, like a spring, a pendulum, something spinning, or a wave. Frequency is equal to 1 divided by the period, which is the time required for one cycle.

The derived SI unit for frequency is hertz, named after Heinrich Rudolf Hertz (symbol hz). One hz is one cycle per second.

f = frequency, the cycles in a unit of time

T = period, the time required for one cycle

N = a number of cycles

t = an amount of time
