An object moving faster than the speed of sound. This object is called:
Correct answer: B. Supersonic
- A. Sonic
- B. Supersonic
- C. Hypersonic
- D. Ultrasonic
- E. infrasonic
Explanation
When an object is moving faster than the speed of sound in a medium, it is considered supersonic. The speed of sound varies depending on the medium, but in the air at sea level, it is approximately 343 meters per second. If an object exceeds this speed, it is said to be supersonic. So option B is correct.

About Electromagnetic Waves
Electromagnetic waves consist of mutually perpendicular, oscillating electric and magnetic fields that also remain perpendicular to the direction of propagation. They travel through vacuum at the speed of light and include radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. Unlike mechanical waves, they do not require a material medium.
