Which of the following is carried by waves from one place to another?

Options

A. Mass
B. Velocity
C. Wavelength
D. Energy

Explanation

To solve the question "Which of the following is carried by waves from one place to another?", we can follow these steps:

### Step 1: Understand the Concept of Waves
Waves are disturbances that travel through a medium (like air, water, or solids). They transfer energy from one location to another without the permanent displacement of the medium itself.

**Hint:** Remember that waves involve oscillations or vibrations, but the medium itself does not move along with the wave.

### Step 2: Identify What Waves Carry
When a wave propagates, it carries energy. This energy is associated with the disturbance caused by the wave as it travels through the medium.

**Hint:** Think about how sound waves can carry energy that can be heard as sound, even though the air molecules themselves do not travel with the wave.

### Step 3: Analyze the Options
1. **Mass**: Waves do not carry mass. The particles of the medium oscillate around their equilibrium positions but do not travel with the wave.
2. **Velocity**: While waves have a velocity, it is not something that is carried from one place to another; rather, it describes how fast the wave travels.
3. **Wavelength**: This is a characteristic of the wave, not something that moves from one place to another.
4. **Energy**: This is the correct answer, as waves carry energy from one location to another.

**Hint:** Focus on what is fundamentally transferred by the wave rather than the properties or characteristics of the wave itself.

### Step 4: Conclusion
Based on the analysis, the correct answer is that waves carry **energy** from one place to another.

**Final Answer:** The correct option is **Energy** (Option 4).
