Electromagnetic radiation with mimimum wavelength is

Options

A. cosmic rays
B. microwaves
C. `gamma` -rays
D. X-rays

Answer

To determine which type of electromagnetic radiation has the minimum wavelength, we can follow these steps:

### Step 1: Understand the Electromagnetic Spectrum
The electromagnetic spectrum is a range of all types of electromagnetic radiation, which includes various types of waves categorized by their wavelengths and frequencies. The spectrum is typically arranged from shortest wavelength to longest wavelength.

### Step 2: Identify the Types of Radiation
The types of electromagnetic radiation in the spectrum include:
- Cosmic Rays
- Gamma Rays
- X-Rays
- Ultraviolet (UV) Rays
- Visible Light
- Infrared Rays
- Microwaves
- Radio Waves

### Step 3: Analyze Wavelengths
In the electromagnetic spectrum:
- Cosmic Rays have the shortest wavelengths.
- Gamma Rays follow, with slightly longer wavelengths.
- X-Rays have longer wavelengths than Gamma Rays.
- UV Rays, Visible Light, Infrared, Microwaves, and Radio Waves have progressively longer wavelengths.

### Step 4: Determine the Minimum Wavelength
Since we are looking for the type of electromagnetic radiation with the minimum wavelength, we can conclude that:
- Cosmic Rays have the shortest wavelength of all the types of radiation listed.

### Conclusion
Therefore, the electromagnetic radiation with the minimum wavelength is **Cosmic Rays**.
