But if an apple has a 1 kg mass and an orange has a 1 kg mass, I seem to be missing any difference.9,192,631,770 Hz /s299 792 458 m/sare both speeds.

and the base unit of 1 second is the same, a rate is repeat occurrence over 1 second, so it is a speed is it not?

Ir = I0/r2 in my universe. What happens in yours?

What happens in yours?I can't read your equation, I presume (I ) is imaginary number?Since your post asked about the intensity of light, a reasonable man would have concluded that I in the answer was intensity. Conventionally we use lower case i or j to indicate an imaginary number.

Quote from: Thebox on 31/01/2016 15:24:53and the base unit of 1 second is the same, a rate is repeat occurrence over 1 second, so it is a speed is it not?Speed can be defined as an object covering a distance in a set amount of time. Enter the second in our calculations. However, the Hertz is defined as a cycle of events over a set amount of time. Where speed is reckoned using distance divided by time, the Hertz is reckoned by a number of events divided by time. Time is the only thing these two have in common. Distances and cycles of events are as different as apples and oranges.
The cycles still travel a distance from A to B?
Quote from: Thebox on 31/01/2016 15:48:21The cycles still travel a distance from A to B?No,.......cycles don't travel. Example: In alternating current, the reversal of current from positive to negative occurs 60 time a second. What you are confusing is; It's not the frequency that travels, it's the current. And current is a flow of electrons through a wire. While the current does travel a distance, the cycle of Hertz only defines the alternation of that direction. You can't apply a value of distance to frequency because frequency only defines a change in direction, as in current flow, or some other change in a physical quality.Until you finally accept the current definitions for these physical qualities, your confusion will only grow Mr. Box.
I have still not had a direct answer to my question, is distance an invariant?
added - hang on a nitting picking moment, I thought a frequency had a wave-length?

I must be reading this link wrongly that would be so preposterous.
Quote from: Thebox on 31/01/2016 19:58:12I must be reading this link wrongly that would be so preposterous.Not preposterous at all Mr. Box, it's a fact. For an observer of that event, length contraction is a reality. However, for the moving object, no noticeable change would be evident. If you contend that Wikipedia and all other scientific source material is preposterous fiction, you then categorize yourself as the only authority. I prefer to stick with well acknowledged and accredited sources.You're wasting our time here Mr. Box. There is an old saying: "A word to the wise is sufficient."How many thoughtful words will we have to expend for you to fall into that category?
You want me to accept something that I either do not understand or something that goes against normal logic and observation.

However, a length and a distance are 2 different things. A length is a measurement of matter, and a distance is a measurement of space.
