Microwaves are the electromagnetic waves with frequency, in the range of

Options

A. micro hertz
B. mega hertz
C. giga hertz
D. hertz

Answer

To determine the frequency range of microwaves in the electromagnetic spectrum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Electromagnetic Spectrum**: The electromagnetic spectrum consists of various types of electromagnetic waves arranged according to their frequency and wavelength. The order from highest frequency to lowest frequency is: gamma rays, X-rays, ultraviolet rays, visible light, infrared radiation, microwaves, and radio waves.

2. **Identify the Position of Microwaves**: In the electromagnetic spectrum, microwaves are positioned after infrared radiation and before radio waves. This positioning helps us understand their frequency range.

3. **Determine the Frequency Range**: Microwaves typically have frequencies ranging from 300 MHz (megahertz) to 300 GHz (gigahertz). This means that the lower limit of microwave frequency is 300 MHz, and the upper limit is 300 GHz.

4. **Conclude the Frequency Range**: Therefore, the frequency range of microwaves can be summarized as 300 MHz to 300 GHz.

### Final Answer:
Microwaves are the electromagnetic waves with frequency in the range of **300 MHz to 300 GHz**.
