Find the resultant of the superposition of two harmonic waves in the form 𝐸 = 𝐸0 𝑐𝑜𝑠 𝑐𝑜𝑠 (𝛼 − 𝜔𝑡) ,with amplitudes of 3 and 4 units and phases of 𝜋6 and 𝜋2 respectively. Both waves have a period of 1 s

Two sinusoidal waves 𝑦1 (𝑥, 𝑡) and 𝑦1(𝑥, 𝑡) have the same wavelength and travel together in the samedirection along a string (say in x-direction). Their amplitudes are 𝑦10 = 4 𝑚𝑚 and 𝑦20 = 3 𝑚𝑚, and theirphase constants are 0 and 𝜋3 respectively. Find the amplitude and phase constant of the resultant wave andexpress the resultant in the standard wave format

Light waves from two coherent sources superimpose at a point. The waves, at this point, can be expressed as `y_(1) = a sin [10^(15) pi t]` and `y_(2)a sin [10^(15) pi t + phi]`. Find the resultant amplitude if phase difference `phi` is (a) zero (b) `pi//3` (c) `pi` Also find the frequency (Hz) of resultant wave in each case.

A longitudinal wave is represented by the equation z(z, t) = −2.0 cm sin(1,200 rad/s t − 20 m−1 z). Another longitudinal wave is represented by the equation z(z, t) = +2.0 cm sin(1,200 rad/s t + 20 m−1 z). What is the equation that represents the superposition of the two waves?
