[Intro]
What is the speed of light
(Is your speed of light right?)
[Verse 1]
Did you assume
You’re in a vacuum?
How can that be
When here’s you and me
[Chorus]
What is the speed of light
(Is your speed of light right?)
Is your constant inconstant
(Does your thought take flight?)
[Bridge]
Causes light to bend
(Are our thoughts on the mend)
On reflection of refraction
(In retraction)
[Verse 2]
A new thesis
Its speed decreases
Out of the vacuum
In a new medium
[Chorus]
What is the speed of light
(Is your speed of light right?)
Is your constant inconstant
(Does your thought take flight?)
[Bridge]
Causes light to bend
(Are our thoughts on the mend)
On reflection of refraction
(In retraction)
[Chorus]
What is the speed of light
(Is your speed of light right?)
Is your constant inconstant
(Does your thought take flight?)
[Bridge]
Causes light to bend
(Are our thoughts on the mend)
On reflection of refraction
(In retraction)
[Outro]
What is the speed of light
(Incite insight in sight)
[Fade]
[End]
A SCIENCE NOTE
Light does not always travel at the same speed.
The speed of light in a vacuum is constant at approximately 299,792 kilometers per second (c). However, when light passes through materials such as water, glass, or air, its speed decreases depending on the material’s refractive index. For example, light slows down significantly in diamond, which has a high refractive index, compared to air. This change in speed is also what causes light to bend (refraction) when entering a new medium.
