Options

A. matter
B. energy
C. energy and matter
D. energy, matter and momentum

Explanation

To solve the question regarding the propagation of a longitudinal wave through a material medium, we will analyze the quantities transmitted in the direction of propagation step by step.

### Step 1: Understanding Longitudinal Waves
Longitudinal waves are characterized by the oscillation of particles in the medium parallel to the direction of wave propagation. In these waves, regions of compression and rarefaction alternate as the wave travels through the medium.

**Hint:** Recall that in longitudinal waves, the motion of the medium's particles is parallel to the direction of wave travel.

### Step 2: Identifying the Key Quantities
In a longitudinal wave, the primary quantities that are transmitted along with the wave are energy and momentum. The energy is transmitted through the oscillations of particles, which create areas of high pressure (compressions) and low pressure (rarefactions).

**Hint:** Think about what happens to the particles in the medium as the wave passes through. Do they move with the wave or just vibrate in place?

### Step 3: Analyzing the Role of Matter
It is important to note that while energy and momentum propagate through the medium, the matter itself does not travel with the wave. Instead, the particles of the medium oscillate around their equilibrium positions, transferring energy through collisions with neighboring particles.

**Hint:** Consider the difference between the movement of energy and the movement of particles in the medium.

### Step 4: Conclusion on Transmitted Quantities
From the analysis, we conclude that the quantities transmitted in the direction of propagation of a longitudinal wave are:
- Energy
- Momentum

Matter does not propagate; it only oscillates around its mean position.

**Hint:** Remember that in wave mechanics, the distinction between energy transfer and material transfer is crucial.

### Final Answer
The correct answer to the question is that the quantities transmitted in the propagation direction of a longitudinal wave are energy and momentum, while matter does not propagate.
