The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.
Light is faster than sound
Full Sail!
of cousre they all are. The only energy like light and sound
While passing through glass.
No. A light year is a measure of distance, not time; it is the distance that light travels in a year. So a cubic light year is a measure of volume, rather like a cubic foot or cubic meeter only much larger.
sound is form of energy and sound reflects a hard surface just like light
Actually it cant be changed unless you move it for the light and the sound is like in echos get it.
Just make your voice light but not too light
they both can be reflected sound would be reflected as an echo and light like when you flash a flash light at a mirror
Kind of like a piccolo and kind of like an orcania, but not the same.
Light can exist without sound. A fluorescent light is an example of this. But yes, light can exist before sound. Light and sound are created simultaneously by something like lightning. It's just that the light is propagated much faster than the sound. We all know that we see the flash of lightning before we hear the sound it makes, and we can "calculate" the distance to the bolt by simple mathematical means.
No. Sound travels slowly like a turtle, while light zips along like a rabbit.
Light has waves right? And sound have waves. If you shine like a laser, a very strong laser, the light waves maybe so strong that is could vibrate the air around it, causing sound
The sound of a 90 year-old climaxing.
you don't have to exactly sound like the chippets when talk tp people. Just make you're voice deep, or light/
1 light hour like how a light year is how far light travels in a year.
