Figure shows a snapshot for a travelling sine wave along a string. Four elemental portions $a, b, c$ and $d$ are indicated on the string. The elemental portion which has maximum potential energy is/are
- ✓$a$
- B$b$
- C$c$
- D$b$ and $d$
✓
Answer
Correct option: A.
$a$
a
(a)
(a)
Maximum potential energy is stored where kinetic energy, i.e., velocity is zero as the total energy of an element of a wave is constant in its oscillating direction.
