Question 28 POST_UTME_OAU • 2020 • PHYSICS • objective

A wave of frequency $f$ and amplitude $A$ is described by the equation $y = A \sin $ 2\pi ft $$. If the wave is reflected from a fixed \end, find the equation of the reflected wave.

Correct Answer A. $y = A \sin \( 2\pi ft + \pi)\ $

B. $y = A \sin \( 2\pi ft - \pi)\ $

C. $y = A \sin \( 2\pi ft + 2\pi)\ $

D. $y = A \sin \( 2\pi ft - 2\pi)\ $

Correct Answer

Correct Option:

$y = A \sin \( 2\pi ft + \pi)\ $
