Frequency (f) = 2.30 GHz = 2.30 × 10^9 Hz

We know that,

Speed of light (c) = 3.00 × 10^8 m/s

Wavelength (λ) can be calculated using the formula:

λ = c/f

Substituting values:

λ = (3.00 × 10^8 m/s) / (2.30 × 10^9 Hz)

λ ≈ 0.13043 meters

To convert meters to nanometers, we multiply by 10^9:

λ = 0.13043 m × (10^9 nm / 1 m)

λ ≈ 130,430,000 nm

Therefore, the wavelength of the microwave at 2.30 GHz is approximately 130,430,000 nanometers.
