A ______ is a disturbance that moves through a medium when the particles of the medium set neighbouring particles into motion.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer: Option 2: Wave
Explanation: According to the laws of physics, a wave is a way of transferring energy. When particles in a medium (such as air, water, or solid) transfer energy to neighboring particles, a disturbance is created that propagates forward. Importantly, the particles in the medium themselves do not travel from one place to another; they only vibrate in place.
Additional Facts:
Types of Waves: There are two main types—transverse, such as light, and longitudinal, such as sound.
Frequency: The number of vibrations per second is called frequency.
Need for a Medium: Mechanical waves (such as sound) require a medium to travel, while electromagnetic waves (such as light) do not.
Possible Questions for the Upcoming Exam:
Why can't sound waves travel in a vacuum?
(Answer: Because there are no particles to carry the disturbance forward.)
Light is an example of what type of wave?
(Answer: Transverse/Electromagnetic).
