What happen to the speed of sound in the air when the temperature goes down?
If the temperature goes down, the speed of sound goes also down. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Do sound waves increase or decrease above sea level?
The sound has really nothing to do with sea level, but changes with temperature alone. The speed of sound goes up when the temperature goes up and goes down when the temperature goes down. The frequency of sound columns, like of woodwinds or of church organs changes with temperature. If the temperature increases, the frequency increases also.
Does light waves or sound waves travle faster?
Light travels much, much faster than sound. Light travels at 299792458 m/s while sound only goes 340.29 m/s.
The sun goes down you feel the light betray you?
No.
Why do you hear a strike half-second after something hits an object?
Because light is faster than sound. We see by light and hear by sound. Light goes approximately 299,792,458 meters per second while sound only goes 340.29 meters per second. Thus the light bouncing off the strike is much faster than the sound that comes from it and so we see faster than we hear.
How does sounds form?
sound form by it's vibration and it goes up and down
Why do you often see a plane before you hear it?
Light travels much faster than sound. Light goes 186,000 miles per second. Sound travels at about 720 miles an hour. The light reaches your eye long before the sound gets there.
What slows down the speed of light?
Light will slow down if it goes through just about anything that is not a vacuum, for example air, glass, water.
Do water vapor clouds slow the speed of light down?
Yes. Light goes slower in water.
How far does light travel in the time it takes sound to travel 1 cm in air at 20 C?
Based on the speed of sound being 340 m/s and that of light being 299,792,458 m/s. we get the speed of light being ~881,742 times that of sound. So if sound goes 1cm then light will travel 881,742 cm or 8,817.42 m.
Why doesn't the color of the police car change when the pitch of its siren goes up or down?
The frequency/wavelength of LIGHT is so high compared to sound that it requires much more velocity to experience the Doppler Effect with light. A car does not nearly approach that speed.
What nicknames does Dennis Jay Funny go by?
Dennis Jay Funny goes by DJ Funny, Funny, and D-Fun.
