How does the sun give light to different parts of the Earth at the same time?
Why is it useful to examine the universe using parts of the electromagnetic spectrum other than visible light?
Different parts of the electromagnetic spectrum give different types of information. Different parts of the electromagnetic spectrum give different types of information. Different parts of the electromagnetic spectrum give different types of information. Different parts of the electromagnetic spectrum give different types of information.
All electromagnetic waves are the same physical phenomenon, existing in a huge range of wavelengths. But we give different names to different parts of the range, according to their characteristics and uses. Some of the names we give to different parts of the range of wavelengths include "radio", "heat", "light", "X-ray", and "gamma ray".
The Little Dipper is a constellation, a patterns of stars in the night sky that people pick out. It is not possible to give a distance of a constellation from Earth because it consists of many stars at very different distances from the earth. For example, Polaris, the brightest star in that constellation, is about 433 light years from Earth. But the second brightest star, Beta Ursae Minoris (also called Kochab) is about 131 light…
Its all to do with the composition of the star, the different elements present in the star will give of different spectra - spectroscopy. Different atoms and molecules give off energy, relating to the unique arrangements of electrons in orbit around their nucleus, the higher energy will be towards the blue end of the spectrum and the lower energy towards the red end. So the light received from a star will show what atoms are…
What measurement tool would give different results on the International Space Station than on earth even when measuring the same object?
When it is day in America it is night in India due to the rotation of the earth. The earth rotates on its axis once a day. Half of the earth is dark while the other half is full of light. America and India are in totally different sun positions which cause day time in America to be night time in India.
How do stars like the sun give us light and how long does it take for that light to arrive on Earth?
Earth - Sun distance (93,000,000 miles) divided by speed of light (186,282 miles per second) equals 8.32 minutes. Some stars we see in the night sky have been gone for eons...the last bits of light they sent our way just haven't arrived yet. As for the light itself, it is merely one of many different forms of energy arriving at the Earth from our sun and countless other stars. It just happens to be a…
Yes. The sun is a giant ball of burning gas, giving off light on its own. However, the moon is a chunk of rock orbiting the Earth. It does not give off light, rather, it is lit up by the light given off by the sun, so that we can see it. The amount of moon we can see is determined by the angles involved with the sun, moon and us.
