Which of the following has shortest wavelength, microwave, ultraviolet wave and X-rays?

Answer

To determine which of the given electromagnetic waves—microwave, ultraviolet wave, and X-rays—has the shortest wavelength, we can follow these steps:

### Step 1: Understand the Electromagnetic Spectrum
The electromagnetic spectrum is a range of all the different frequencies of electromagnetic radiation. It includes various types of waves, arranged in order of increasing frequency and decreasing wavelength.

### Step 2: Identify the Position of Each Wave in the Spectrum
1. **Microwaves**: These waves have longer wavelengths, typically ranging from about 1 millimeter to 1 meter.
2. **Ultraviolet Waves**: These waves have shorter wavelengths than microwaves, typically ranging from about 10 nanometers to 400 nanometers.
3. **X-rays**: These waves have even shorter wavelengths, typically ranging from about 0.01 nanometers to 10 nanometers.

### Step 3: Compare the Wavelengths
From the information gathered:
- Wavelength of microwaves > Wavelength of ultraviolet waves > Wavelength of X-rays.

### Step 4: Conclusion
Since X-rays have the shortest wavelength compared to both microwaves and ultraviolet waves, we conclude that **X-rays have the shortest wavelength** among the three.

### Final Answer
**X-rays have the shortest wavelength.**
