To calculate the wavelength of a microwave given its frequency, you can use the formula:
Wavelength (λ) = Speed of Light (c) / Frequency (f)
The speed of light (c) is approximately 3.00 x 10^8 meters per second.
Let's plug in the values:
λ = (3.00 x 10^8 m/s) / (4.2 x 10^8 Hz)
Calculating the result:
λ ≈ 0.714 meters
Therefore, a microwave with a frequency of 4.2 x 10^8 Hz has a wavelength of approximately 0.714 meters.
