State the name and the range of wavelength of the invisible electromagnetic waves beyond the red end of the visible spectrum

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Electromagnetic Waves:**
- The question asks for the name of the invisible electromagnetic waves that are located beyond the red end of the visible spectrum. These waves are known as **infrared radiation**.

2. **Determine the Wavelength Range:**
- The next part of the question requires us to state the range of wavelengths for infrared radiation. The typical range for infrared radiation is from approximately **800 nanometers (nm)** to **1 millimeter (mm)**.

3. **Convert Units if Necessary:**
- It is important to note that 1 millimeter is equal to 1,000,000 nanometers (or \(10^6\) nm). Therefore, the range can also be expressed as:
- **800 nm to \(10^7\) nm** (which is equivalent to 1 mm).

4. **Final Statement:**
- Thus, the invisible electromagnetic waves beyond the red end of the visible spectrum are called **infrared radiation**, with a wavelength range of **800 nm to 1 mm** (or **800 nm to \(10^7\) nm**).

**Final Answer:**
- The name of the invisible electromagnetic waves beyond the red end of the visible spectrum is **infrared radiation**, and their wavelength range is from **800 nm to 1 mm**.
