The correct statement among the provided options is:
Microwaves have lower frequencies than visible light waves. Since frequency and wavelength are inversely proportional, microwaves also have longer wavelengths than visible light waves.
- Microwaves indeed have lower frequencies compared to visible light waves.
- Frequency and wavelength are inversely proportional, which means that if the frequency decreases, the wavelength increases. Therefore, microwaves have longer wavelengths than visible light waves.
None of the provided responses directly contain this exact phrasing; however, the first choice seems to incorrectly state that microwaves have shorter wavelengths, which is false. Please double-check the text of the answer choices as they may contain errors or duplicates.
