Final answer:
Engineers use higher-frequency electromagnetic waves to send information because they can carry more data, travel longer distances without losing signal strength, and offer better resolution and accuracy in certain applications.
Step-by-step explanation:
Engineers opt to use higher-frequency electromagnetic waves to send information because higher-frequency waves have a shorter wavelength and can carry more information in a given amount of time. This is known as the bandwidth of the wave. By using higher-frequency waves, engineers can transmit more data, such as audio, video, and images, in a shorter amount of time.
Additionally, higher-frequency waves have higher energy levels, which means they can travel longer distances without losing signal strength. This is particularly important in long-range communication systems, such as satellite communication and wireless networking.
Furthermore, higher-frequency waves also offer better resolution and accuracy in certain applications. For example, in radar systems, higher-frequency waves can provide finer detail and detection capabilities, allowing engineers to accurately locate moving targets and track their movements.
