Final answer:
Ground waves produce better images compared to sky waves because they are less prone to interference and signal degradation.
Step-by-step explanation:
When it comes to producing better images, ground waves are generally preferred over sky waves. Ground waves are also known as surface waves and travel along the surface of the Earth. They can propagate over long distances and are used for broadcasting radio signals. On the other hand, sky waves are a type of ionospheric wave that reflects off the ionosphere and returns to the Earth's surface. While sky waves allow for long-distance communication, they tend to be more prone to interference and signal degradation compared to ground waves.
