Because of tilting, which waves finally disappear?

Options

A. Micro waves
B. Surface waves
C. Sky waves
D. Space waves

Answer

To solve the question "Because of tilting, which waves finally disappear?", we can follow these steps:

### Step 1: Understand the Types of Waves
Identify the types of waves mentioned in the question: microwaves, surface waves, sky waves, and space waves. Each of these waves has different propagation characteristics.

### Step 2: Analyze the Effect of Tilting
Recognize that tilting refers to the change in orientation of the waves as they propagate. This can affect how the waves travel and their energy levels.

### Step 3: Focus on Surface Waves
Surface waves, also known as ground waves, propagate along the surface of the Earth. They are affected by the Earth's surface and can undergo diffraction, which is the bending of waves around obstacles.

### Step 4: Consider the Impact of Increasing Tilt Angle
As surface waves propagate, the tilt angle increases. This increase in tilt can lead to a reduction in the energy of the surface waves. If the tilt becomes too great, the energy may dissipate to the point where the waves can no longer be effectively transmitted.

### Step 5: Conclude the Answer
Based on the analysis, we conclude that the waves that finally disappear due to tilting are the surface waves.

### Final Answer
The correct answer is **surface waves**.
