Explanation:
ultraviolet waves
light waves
sound waves
Ultrasounds are used in the medical profession for the purpose of diagnosis. Ultrasounds uses high frequency sound waves. Thus, the correct option is D.
Ultrasound are the sound waves with frequencies which are higher than the upper audible limit of normal human hearing. Ultrasound is not different from normal audible sound frequencies in its physical properties, except that humans cannot hear these sound.
Ultrasound is used in diagnostics where it is also called as sonography or diagnostic medical sonography. It is an imaging method which uses sound waves to produce images of structures within the body of a person. The images produced can provide valuable information for the purpose of diagnosing and directing treatment for a variety of diseases and conditions.
Therefore, the correct option is D.

The complex balancing act between a satellite's forward speed and the gravitational force pressing upon it prevents satellites in orbit from falling to the ground or shooting off into space.
When a satellite is put into orbit, it reaches a fast enough speed to escape the Earth's gravitational attraction.
By continuously falling towards the Earth and moving forward at the same time, the satellite may maintain a stableorbit.
This motion results in a curved course, which causes the Earth to be in a constant state of freefall.
Although the satellite is constantly being drawn towards the Earth by gravity, its forward velocity prevents it from dropping.
Thus, satellites don't fall or break free into space and are kept in a stable orbit.
