Why does light from stars arrive at a telescope as parallel rays?
Light from stars arrives at a telescope as parallel rays because stars are very far away compared to the size of a telescope's aperture. This distance makes the light rays effectively parallel when they reach the telescope, similar to how sunlight reaches Earth as parallel rays.
If everyone on earth was to shout how far will the sound travel by distance?
around the world 26,000 miles
How far did Apollo 12 travel?
Apollo 12 traveled to the moon and back to earth.
How far away is the sun in light minutes?
The sun is about 8.3 light minutes away from Earth. This means that it takes about 8.3 minutes for light to travel from the sun to Earth.
How far does the earth travel in one week?
The Earth travels approximately 940 million kilometers (584 million miles) around the Sun in one week as it completes one full orbit.
How does the effect of the suns gravity on Pluto compare to the effect of the suns gravity on earth?
well pluto is so far away that the sun rays can't reach out that far for it to be warmer and for earth,the earth is much closer and could get most of the suns hot rays
How far do suns direct rays travel in a year?
About 9.45 trillion kilometers (5.88 trillion miles) per year if you mean how far can light (including the sun's light) travel in a year. 365 days/year * 86,400 seconds/day * 299,792 km/s = 9.45 x 10^12 km/year
How far do x-rays travel?
Potentially to the ends of the universe.
What will happen if there is no UV rays?
Although it is harmful, it's still important. UV rays carries heat from the sun. Although the sun is the closest star from earth, it's still far away and it's almost about 150 million kilometers away from the sun and sunlight itself can't travel that far because the sun's surface is only about several thousand degrees Celsius, that's why they are carried by UV rays, so the earth will have the right temperature for living. If there is no UV rays, Earth will be like Pluto. UV rays can't travel more than a billion kilometers and Pluto is 7.4 billion kilometers away, so UV rays can't reach Pluto.
The part of the earth where the sun's rays strike most directly is called?
The top of Everest, K2, Kilimanjaro or any high mountain. This is due to a lack of particulates in the air to filter the rays out and of course because they are closer to the sun. Although the Equatorial region of the Earth may be the hottest, the actual difference in distance between the Equator and Everest is negligible if you consider how far the suns rays have travelled to get to us in the first place.
How far a gamma ray can travel?
Gamma rays can travel long distances through space, potentially millions of light years, due to their high energy and lack of mass. On Earth, the distance gamma rays can travel depends on the material they encounter, with higher-energy gamma rays penetrating further than lower-energy ones. In dense materials like lead, gamma rays may only penetrate a few centimeters, while in air they can travel several meters.
How does the angle at which the Suns rays strike the earth affect the temperature at earth surface?
If the sun's rays hit the Earth's surface at a direct spot, which is usually around the equator, that area would be the warmest. Any area that is far away from the sun's rays is usually cold.
How far does earth travel in one second?
29.782Mph
Does earth have rays?
Yes, Earth receives various types of rays from the sun, such as visible light, ultraviolet rays, and infrared radiation. These rays play a role in sustaining life on our planet by providing energy for photosynthesis and regulating the climate. Earth's atmosphere also helps to filter out harmful rays, like most of the sun's ultraviolet radiation.
When stars fall do they become rocks?
No. Stars cannot fall to Earth They are far beyond the influence of Earth's gravity and far larger and more massive than Earth. The stars are suns, some larger and brighter than our own but unimaginably far away. The remains of dead stars are composed of extremely dense forms of matter not found on Earth. The "falling stars" are not actually stars; they are meteors, small pieces of rock and metal that burn up as they travel through Earth's upper atmosphere at extreme speeds.
How far will gamma travel?
Gamma Rays will travel as long as they have energy
How far does light travel to get to earth?
It takes 8 minutes from the Sun
