1. What is Microwave Oven Frequency?

Most microwave ovens operate at a frequency of approximately 2.45 GHz. This frequency is specifically allocated for industrial, scientific, and medical (ISM) applications, making it ideal for microwave cooking.

2. How Does the Calculator Work?

The calculator converts the microwave frequency between different units:

And calculates wavelength using:

Where:

• \( \lambda \) — Wavelength (meters)
• \( c \) — Speed of light (3 × 10⁸ m/s)
• \( f \) — Frequency (Hz)

3. Importance of 2.45 GHz Frequency

Details: The 2.45 GHz frequency is particularly effective for heating water molecules in food, as water absorbs electromagnetic radiation efficiently at this frequency. This ISM band is also used for WiFi and Bluetooth devices.

4. Using the Calculator

Tips: Enter the frequency in GHz (default is 2.45 GHz for microwave ovens). The calculator will automatically convert to MHz, Hz, and calculate the corresponding wavelength.

5. Frequently Asked Questions (FAQ)

Q1: Why exactly 2.45 GHz?
A: This frequency was chosen because it efficiently heats water molecules while penetrating deep into food, and it's in an internationally allocated ISM band.

Q2: Are all microwave ovens exactly 2.45 GHz?
A: Most consumer microwave ovens operate around 2.45 GHz, but there may be slight variations. Industrial models may use different frequencies.

Q3: What is the wavelength at 2.45 GHz?
A: Approximately 12.2 centimeters, which is why microwave ovens have specific cavity sizes and turntables.

Q4: Can microwave frequency be changed?
A: No, microwave ovens are designed to operate at their specific frequency and changing it would require significant modifications.

Q5: Is 2.45 GHz safe for other devices?
A: Microwave ovens are shielded to prevent interference, but leakage can potentially affect nearby WiFi signals operating in the same band.
