The speed of light is
[ 299,792,458/the refractive index of the medium ] meters per second.
I hope this statement has some relevance to the question.
Hz (hertz) is a unit of frequency, not of speed.
the speed of light is 299,792,458 metres per second
Sound . . . 0.34 km/second Light . . . . 300,000 km/second
The speed of light in vacuum is 299,792,458 m/s usually rounded to 300,000 km/sec.The speed of sound at sea level is 343 m/s.The difference is 299,792,115 m/s.That's 99.999 886 % of the speed of light, and may also be rounded to 300,000 km/sec.
The speed of light is about 300,000 kilometers per second (3 x 108 meters per second); the distance light travels in a year is called a light-year. It is equivalent to about 9.5 x 1015 meters.
Energy is directly proportional to the square of the speed of light (in vacuum), where the constant of proportionality is the mass equivalent of the energy.
Hz (hertz) is a unit of frequency, not of speed.
Energy has an equivalent mass; you can divide energy (in Joule) by the square of the speed of light (the square of 300,000,000 m/sec). The result is in kilograms.Energy has an equivalent mass; you can divide energy (in Joule) by the square of the speed of light (the square of 300,000,000 m/sec).

That is approximately equivalent to 1 light-year. That is to say, if travelling at the speed of light - the highest possible speed in the Universe - it will take a year to get there.
1.5 million light-years is equivalent to the distance that light travels in 1.5 million years.
Is what the speed of light or light speed.ANSWER300,000 km/s

Energy equals mass times the speed of light squared. Energy and mass are equivalent.
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
