What happens to the sound an object makes when the speed of vibrations decreases slow down?
Explanation: because when the speed of vibrations decrease the pitch of sound becomes lower tone.
How do air molecules enable sound to travel?
How do air molecules enable sound to travel from a radio’s speaker to your ears? They push together and apart allowing the sound wave to travel as it vibrates from the radio speaker to your ear. Describe a compression and a rarefaction of a sound wave traveling through the air.
Can you hear yourself talk in space?
So, Alien has it right; while it’s not strictly true that sound waves can’t travel through space, it is true that humans would not be able to hear those sounds. Scream all you want, no one is hear you. Radio waves can travel through space because they’re electromagnetic, not mechanical, and can travel through a vacuum.
Can sound kill you?
Yes. Sound can absolutely kill you if it’s loud enough. Sound is created by a pressure wave which vibrates particles as it travels in an accordion-like manner. A vibrating source pushes particles forwards with a high-pressure wave.
How loud is the sun in space?
Sound intensity decreases with distance, which means that the Sun would deliver a much smaller 125 decibels to the surface of our planet. In comparison, 120 decibels is a train horn about one metre away whereas 130 decibels is physical pain. In general, the lower the pitch, the bigger the star.
Why can’t we hear the explosion on Sun?
Originally Answered: Why doesn’t the noise of explosions on the sun reach us? Because sound cant propagate through vacuum. Sound is a mechanical wave and every mechanical wave needs a medium through which it can propagate. There is no sound in space because there is no medium through which sound can spread.
How close do you have to be to the sun to hear it?
Four million miles (or if you prefer, 6.44 million kilometers) is quite a distance. It’s the equivalent of driving around Earth’s widest point, the equator, 160 times in a row. Well that’s about as close to the sun as NASA is willing to take its new Parker Solar Probe (PSP).
How long would it take for us to notice the sun exploded?
eight minutes and 20 seconds
Would we see the sun explode?
With a name like ‘Supernova,’ you’d think that a solar explosion would be the most magnificent fireworks show the world has ever seen. But in reality, you likely wouldn’t see anything! The Sun is 150 million km (93 million miles) away from Earth, and it takes 8 minutes for light from the Sun to reach us.
What if the sun was blue?
A blue sun wouldn’t change that. Since blue stars burn hotter then red and yellow stars the Earth would be much hotter to the point that there would be no atmosphere and thus nothing to scatter any light. The sky would be black except for the very intense sun up there.
Is the Blue Sun Real?
When the Sun is high in the sky, the shorter waves, primarily the blue, strike air molecues in the upper atmosphere and bounce around and scatter. Hence explaining why the sky looks blue. Some people think that enough blue light is scattered out in the Earth’s atmosphere to cause the Sun to appear slightly yellow.
Why is there a blue sun?
As the white light from the Sun enters Earth’s atmosphere, much of the red, yellow, and green wavelengths of light (mixed together and still nearly white) pass straight through the atmosphere to our eyes. The scattered violet and blue light dominates the sky, making it appear blue.
What color would plants be if the sun was blue?
Around stars hotter and bluer than our sun, plants would tend to absorb blue light and could look green to yellow to red. Around cooler stars such as red dwarfs, planets receive less vis- ible light, so plants might try to absorb as much of it as possi- ble, making them look black. green aliens are so passé.
