Light is a/an

Options

A. Electromagnetive wave
B. infrared wave
C. ultrasonic wave
D. X-Ray

Answer

To solve the question "Light is a/an," we need to analyze the options provided and understand the nature of light.

### Step-by-Step Solution:

1. **Understanding Light**:
- Light, in general terms, refers to the visible spectrum of electromagnetic radiation that is detectable by the human eye.

2. **Identifying the Nature of Light**:
- Light is a form of electromagnetic radiation. This means it consists of waves of electric and magnetic fields that propagate through space.

3. **Evaluating the Options**:
- **Option A: Electromagnetic wave**: This is correct because light is indeed an electromagnetic wave.
- **Option B: Infrared waves**: This is incorrect because infrared waves are a type of electromagnetic radiation but are not what we typically refer to as "light."
- **Option C: Ultrasonic wave**: This is incorrect as ultrasonic waves are sound waves, not electromagnetic waves.
- **Option D: X-ray**: This is also incorrect since x-rays are another form of electromagnetic radiation, but they are not the visible light we are discussing.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option A: Electromagnetic wave**.

### Final Answer:
Light is an **electromagnetic wave**.
