EW300 Final Question and answers already passed Do longer or shorter wavelengths "bend" more? - correct answer Longer wavelengths bend more Ground Waves - correct answer Ionosphere and ground form a duct. Lower Frequencies: F <3MHz Sky Waves - correct answer Refracts in Ionosphere and then back to the ground. Frequencies: 3MHz < f < 30MHz Space Waves - correct answer Straight line propagation through Ionosphere. Higher Frequencies: f>30MHz
