Radio waves, Middle-C, and halitosis are not forms of light.
It would be option C. It rotates, or spins, on its axis, but it revolves around the sun.
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of an atom. It is identical to the charge number of the nucleus. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons.
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.
