Question

2 in what direction is matter displaced in a transverse wave? a in the same direction as the energy flow b in the opposite direction as the energy flow c in a spiral around the energy flow d at a right angle to the energy flow

Explanation:

To determine the direction of matter displacement in a transverse wave, we recall the definition of a transverse wave: in a transverse wave, the particles of the medium (matter) vibrate perpendicular (at a right angle) to the direction of energy (wave) propagation. Longitudinal waves have matter displacement parallel to energy flow, but transverse waves (e.g., light, water waves) have perpendicular displacement. Option A is for longitudinal (same direction), B is incorrect, C is not a characteristic of transverse waves. So D matches the transverse wave definition.

Answer:

D. At a right angle to the energy flow
