Question
We can ______.
- Not see all wave motions
- Not see few waves
- See all wave motions
- None of these
Hint:
Not see few waves
The correct answer is: Not see few waves
- There are waves everywhere. We all encounter with waves on a daily basis, whether we realise it or not.
- Sound waves, visible light waves, radio waves, microwaves, water waves, waves on a string, and so on are just a few instances of how we interact with waves on a daily basis.
- In addition to waves, there are a range of phenomena in our physical world that might be described as wavelike.
- The movement of a pendulum, the movement of a mass supported by a spring, the movement of a child on a swing and etc.
- We can see only a few like electromagnetic waves are types of energy that are invisible and flow across the universe.
- However, some of the effects of this energy are visible. The light that we see is a component of the electromagnetic spectrum.
