Question 23 of 50 from the Joint Admissions and Matriculation Board (JAMB) Physics 2015 Objective paper, with the correct answer and a full explanation.

A progressive wave is represented by y = 10sin(1000t − πx/34). Two layers of the wave separated by 153cm have a phase difference of

A. 270°Correct
B. 45°
C. 90°
D. 180°

Explanation

Using the wave equation's phase constant, the phase difference for a 153cm separation works out to 270° per the source's calculation.
