In air, the 57 GHz radio wave has a shorter
wavelength compared to the 64 GHz radio wave.

False

Explanation:

Higher frequency signals have shorter wavelengths. Hence, the 64 GHz signal will have a shorter wavelength than the 57 GHz signal.

Frequency and wavelength are inversely proportional meaning as frequency increases wavelength decreases and as frequency decreases wavelength increases.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
