The same speed
2006-10-23 10:31:00 · answer #1 · answered by Polo 7 · 0⤊ 0⤋
The speed of sound thru some medium is proportional to it's density. The more dense something is, the faster the sound travels thru it. Light itself would not have an effect on sound, however during the day (when it's light) the air temperature is generally higher, and that makes the density of the air lower, so sound would travel slower during the day and faster at night. This would be a very small effect however, probably undetectable without very sensitive equipment.

The speed of sound depends on many things, including the density of the medium through which the sound propagates, temperature, pressure etc.
If the question refers to daylight and nighttime then there will be a temperature difference between the two. At about 20 degrees (daytime) the speed of sound is 343 m/s. At about 10 degrees (nighttime) the speed of sound is 337 m/s. This is assuming constant standard atmospheric pressure. Turning the light off in a dark room won't make any difference!

The velocity of sound depends on the density of the medium. The denser the medium, the faster it travels. Since electromagnetic energy has no mass, it has no impact on the speed of sound.

latif_195...
is right i know this because i took a class called space sci, and light has mass, and a gas has mass so 1+1=2 and 2 is grater thin 1. so you can say that sound will travel faster with the light on

Sound doesn't travel through dark or light. It travels through a material medium such as air, water, or steel.

It tries to travel at the same speed (dependant on altitude) at all times. The problem is that at night it gets tired, just like the rest of us.
What it does hate, is not getting paid overtime rates for working the late shift.

This is a good question,
if you want to assume light is matter (which is true)
then air with photos in it is denser that air with out photons in it,
but how much denser?
do we have the equipment to measure such extremely small difference?
the answer is: it should travel faster in light, but only extremely small difference (undetectable)

Undoubtly it doesn't depend on the dark or the light....What are you thinking?About a Thunder...?They seem to be conected but the don't be it!

light, 'cuz it can see where to go
