The equation of the resultant motion of the number of simple harmonic motions is E c ( 1 + K sin ⁡ ω 2 t ) sin ω 1 t . The number of simple harmonic components is/are

Step-by-step solution

Y = E c ( 1 + K sin ⁡ ω 2 t ) sin ω 1 t Y = E c sin ⁡ ω 2 t + E c k sin ⁡ ω 2 sin ⁡ ω 1 t Y = E c sin ⁡ ω 1 t + E c K 2 cos ⁡ ω 2 + ω 1 t E c K 2 ω 2 - ω 1 t Thus there are three simple harmonic waves of frequency ω 1 , ω 1 + ω 2 and ω 1 - ω 2
