answeredThe frequencies of most radiation sources are not affected by the speed of light. However, the speed of light affects the energy levels and resonant frequencies of some devices

Frequency (f) = Speed of light (c) / Wavelength (λ)
Given that the wavelength of the microwave is 3 cm, we can convert it to meters by dividing by 100:
Wavelength (λ) = 3 cm / 100 = 0.03 meters
The speed of light in a vacuum is approximately 3 x 10^8 meters per second (m/s). Therefore, we can calculate the frequency as follows:
Frequency (f) = Speed of light (c) / Wavelength (λ)
f = 3 x 10^8 m/s / 0.03 m
f ≈ 1 x 10^10 Hz
So, the frequency of the microwave is approximately 1 x 10^10 Hz (or 10 GHz).
Now let's consider the hypothetical scenario where the speed of light in air decreases by a factor of 2. In this case, the new speed of light in air would be 1.5 x 10^8 m/s (half of the original value). This means the frequency would still remain the same, as the equation f = c / λ is not affected by any changes in the speed of light in a medium, only by changes in wavelength. Therefore, if the speed of light in air decreased by a factor of 2, the frequency would still be approximately 1 x 10^10 Hz.

frequency = speed of light / wavelength
The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s), which is also equivalent to 2.99792458 x 10^8 meters per second (m/s).
We need to convert the wavelength from centimeters (cm) to meters (m) before calculating the frequency. Since there are 100 centimeters in 1 meter, the wavelength is 0.03 meters.
Plugging in the values into the formula, we get:
frequency = 2.99792458 x 10^8 m/s / 0.03 m ≈ 9.993 x 10^9 Hz.
The frequency of the microwave is approximately 9.993 x 10^9 Hz.
Now, let's consider if physics suddenly broke and the speed of light in air decreased by a factor of 2. In that case, we would need to determine the new speed of light in the given scenario.
If the speed of light in air decreased by a factor of 2, it would mean the new speed of light in air would be halved.
The new speed of light would be 299,792,458 m/s / 2 = 149,896,229 m/s.
Repeating the calculation with the new speed of light, we would get:
frequency = 149,896,229 m/s / 0.03 m ≈ 4.996 x 10^9 Hz.
The new frequency of the microwave with the decreased speed of light in air would be approximately 4.996 x 10^9 Hz.
Therefore, if the physics suddenly broke and the speed of light in air decreased by a factor of 2, the frequency of the microwave would change accordingly.
