Is it true that all radio waves are faster than all sound waves—no exceptions? A) False always.B) True, in most common cases.C) False in some cases.D) True in all cases.
D) True in all cases.
To determine the correct answer, we need to understand the properties of radio waves and sound waves.
Radio waves are a type of electromagnetic wave, while sound waves are mechanical waves. Electromagnetic waves, including radio waves, can travel through a vacuum such as empty space, while sound waves require a medium, such as air, water, or solids, to propagate.
The speed at which waves travel depends on the properties of the medium they pass through. In general, electromagnetic waves, including radio waves, travel at the speed of light, which is about 299,792,458 meters per second in a vacuum.
On the other hand, the speed of sound waves varies depending on the medium they travel through. In air, for example, sound waves typically travel at around 343 meters per second.
Given this information, we can conclude that the correct answer is D) True in all cases. Radio waves, being electromagnetic waves, always travel faster than sound waves. However, it is important to note that the speed at which both radio waves and sound waves propagate can vary depending on the specific medium they travel through.
