Question

The diagram below shows the propagation of a wave. Which points are in same phase?

• A. $B$ and $E$
• B. $F$ and $G$
• C. $C$ and $E$
• D. $B$ and $F$

Answer 1

The correct option is D $B$ and $F$

As we know, from the given diagram the points which are at the same distance $\left(\lambda \right)$ are in same phase.

Therefore, as per diagram, points $B$ and $F$ are in same phase as they are $\left(\lambda \right)$ distance apart.

Final answer: $\left(d\right)$
