Which of the following has a minimum wavelength ?

Options

A. Gamma rays
B. Blue light
C. Infrared rays
D. microwave

Explanation

To determine which of the given options has the minimum wavelength, we can follow these steps:

### Step 1: Understand the Electromagnetic Spectrum
The electromagnetic spectrum consists of various types of electromagnetic waves arranged in order of increasing wavelength. The spectrum includes:
- Cosmic Rays
- Gamma Rays
- X-rays
- Ultraviolet Rays
- Visible Light (which includes colors like violet, blue, green, yellow, orange, and red)
- Infrared Rays
- Microwaves
- Radio Waves

### Step 2: Identify the Wavelengths of the Given Options
The options provided are:
1. Gamma Rays
2. Blue Light
3. Infrared Rays
4. Microwaves

From the electromagnetic spectrum:
- Gamma Rays have the shortest wavelength.
- Blue Light (part of visible light) has a longer wavelength than gamma rays.
- Infrared Rays have an even longer wavelength than blue light.
- Microwaves have the longest wavelength among the options listed.

### Step 3: Compare the Wavelengths
Now, we can compare the wavelengths:
- Gamma Rays: Shortest wavelength
- Blue Light: Longer than gamma rays
- Infrared Rays: Longer than blue light
- Microwaves: Longest wavelength

### Step 4: Conclusion
From the comparison, it is clear that gamma rays have the minimum wavelength among the options provided.

### Final Answer
**Gamma Rays have the minimum wavelength.**
