Post Utme Unilorin 2022 Physics Objective / Multiple Choice
Question 12 POST_UTME_UNILORIN • 2022 • PHYSICS • objective

A wave of frequency $f$ and amplitude $A$ is described by the equation $y = A \sin \( 2 \pi f t \)$, where $y$ is the displacement of the wave at time $t$. If the wave is reflected from a fixed \end, find the equation of the reflected wave.

Answer Options

Correct Answer A. y_{\text{reflected}} = A \sin \( 2 \pi f \( t - \frac{L}{2v} \ \))
B. y_{\text{reflected}} = A \sin \( 2 \pi f \( t + \frac{L}{2v} \ \))
C. y_{\text{reflected}} = A \sin \( 2 \pi f \( t - \frac{L}{v} \ \))
D. y_{\text{reflected}} = A \sin \( 2 \pi f \( t + \frac{L}{v} \ \))
Correct Answer
A
Correct Option:
y_{\text{reflected}} = A \sin \( 2 \pi f \( t - \frac{L}{2v} \ \))
