Quizplus · Accepted Answer

When two waves with the same frequency and amplitude are superimposed, the resulting wave will have a phase angle equal to the phase difference between the two waves. In this case, the phase difference is equal to π/2 radians, which is the same as the given number 11eb6adc_ee7b_4fa1_b0cf_a309e7be5df4_TB8245_11 in hexadecimal notation. Therefore, the answer is choice C.
