The velocity of light is circa 300,000 metres/sec in most environments.

I am most interested in the velocity of light as observed by someone
moving with respect to the light's source.

(BTW: you're off by 1,000.)

Circa means "about", shithead. It may be 200,000 metres/sec in water,
but not too many under water experiments have been carried out.

The refractive index of water is 1.333 or thereabouts. This would
translate into a velocity of about 225,000 km/s.

| OK. So what is light, then? What is wavelength?

Light is electromagnetic energy, the most common form being
solar energy. In case you didn't notice, shithead, sunlight feels warm.
Wavelength is distance. Cars and photons do not possess the
property "distance", shithead, althought they may travel some distance.

What do cars possess then? I can easily measure distances on my car; for
example, axle-to-axle and width of the front seat.

As for photons, that's an interesting question, which I for one am not
sure I can answer effectively, especially given your vast understanding of
the topic.

Equally spaced bumps in the road form a wave and have a distance
between them, which can be called a wavelength.
How old are you, 12?

I'm less than a year old. But it's not an Earth year to which I refer.
