Consider a situation in which two sinusoidal waves of the same wavelength and same amplitude but differ by a phase shift (they are offset along their mutual line of propagation). Which of the following must be true of the resultant summation of these two waves?(1) The resultant wave must have the same amplitude as the individual waves. (ii) The resultant wave must have the same frequency as the individual waves. (iii) The resultant wave must have the same wavelength as the individual waves.Select the correct answerO Only statement (1) is true.O Only statement (ii) is true.O None of these statements are true.O Only statements (i) and (ii) are true.O Only statements (ii) and (iii) are true.O All three statements are true.
