Do you have a book about it? or if you have a dictionary?
Answer:
A constant value everywhere in the universe.
Explanation:
The speed of light in a vacuum is a constant value. It is not affected by change in frequency or wavelength of the light.
Mathematically the speed of light is given as:
c = λf
where λ = wavelength and f - frequency
The speed of light is the constant of proportionality between frequency and wavelength. In order words, wavelength and frequency are inversely proportional. As the wavelength increases, frequency decreases and vice versa.
While the change in wavelength and frequency of light affect the energy of the light, its speed is a constant value as long as the medium is a vacuum.
The speed of light is also not dependent on the manner with which the light wave is moving.
Whatever phase of the moon Ike sees, he can expect to see
the same phase of moon again, after 29.53 days later.
The velocity of light in glycerol is 2.04 × 10⁸ m/s.
To find the answer, we need to know about the expression of velocity of light in any medium.
<h3>What's the expression of the speed of light in any medium?</h3>
- Mathematically, the speed of light in any medium= C/n
- C = speed of light in vaccum, n = refractive index of the medium
<h3>What's the speed of light in glycerol having refractive index of 1.47?</h3>
Speed of light in glycerol= 3×10⁸/1.47 = 2.04 × 10⁸ m/s
Thus, we can conclude that the velocity of light in glycerol is 2.04 × 10⁸ m/s.
