A pulse travels toward − x . A point on its rising front (positive slope ∂ y / ∂ x ) is instantaneously moving:

For a wave moving to − x the particle velocity is + v ∂ y / ∂ x . A positive slope gives upward velocity.

A pulse travels toward $- x$ . A point on its rising front (positive slope $\partial y / \partial x$ ) is instantaneously moving:

Answer:

Solution:

For a wave moving to $- x$ the particle velocity is $+ v \partial y / \partial x$ . A positive slope gives upward velocity.
