Why does calcite show twinkling effect?
Calcite has a uniaxial indicatrix with a ellipsoid shape. The two permitted vibration directions (transmitting the ordinary and extraordinary rays), cause twinkling to be observed on rotation.
What are the ideal weather conditions for stargazing?
Ideal weather conditions for stargazing include clear skies with minimal light pollution, low humidity to reduce atmospheric distortion, and stable atmospheric conditions to minimize twinkling of stars. Additionally, cooler temperatures can help improve visibility by reducing heat distortion.
What planet has the most stars?
The Milky Way galaxy has the most stars, with an estimated 100 billion stars. There is no planet that has more stars than any other since planets are celestial bodies that orbit stars.
Metals are relatively more abundant in new stars or old stars or neither?
Metals are relatively more abundant in old stars compared to new stars. This is because metals are created through the fusion of lighter elements in the cores of stars, so as stars age and go through multiple cycles of nucleosynthesis, they accumulate more metals. New stars, on the other hand, form from the remnants of previous generations of stars and may have lower metal content.
Why do street lights twinkle at night when you see them from a distance?
For pretty much the same reason that stars do. It's an optical illusion caused by the bending of light through a turbulent and hazy atmosphere. If the unevenly-heated air between you and the streetlights happens to contain a mix of smoke, dust and water vapor, then the churning particles and droplets will act like tiny mirrors, shadows and lenses. This chaotic mix will distort the light rays passing through it, causing faraway light sources to appear to flicker or twinkle. As you move closer to the light, the number of photons reaching your eyes rapidly increases. This tends to average out the apparent intensity of the light, making the twinkling effect 'magically' disappear. (This is also the same way ancient astronomers were able to tell planets from stars, by the way: the planets are close enough to Earth that it took a very turbulent sky indeed to make them appear to twinkle at all.)
Is twinkling of stars caused by reflaction?
twinkling of stars is caused by refraction
What effect causes twinkling of stars?
refraction
What does a string of twinkling stars mean?
Very shiny
Why overhead stars do not twinkle?
Stars are not twinkling really. It is because of the atmosphere of the earth due to which they appear twinkling. However if they are seen from above the atmosphere of earth then they appear stationary.
Is twinkling an adjective?
It is a verb form from the verb twinkle. If it is a present particle, it can be used as an adjective. Example: The twinkling stars filled the night sky. If it is a gerund , it is used as a noun. Example: He disappeared in the twinkling of an eye.
What is the definition of aglitter?
Glittering and twinkling as if you were looking at a lot of stars.
Why would a star not twinkle?
Assuming that other stars in the sky are twinkling at the time what appears to be a star (except it is not twinkling) is probably a planet.
How do you write an essay on how stars twinkle?
To write an essay on how stars twinkle, you can start by explaining the scientific phenomenon behind star twinkling, known as atmospheric turbulence. Discuss how light from stars gets refracted as it passes through Earth's atmosphere, leading to twinkling. Address factors that influence the intensity of twinkling, such as air temperature and wind speed. Conclude by exploring the beauty and symbolism of stars twinkling in the night sky.
Why do stars appears in the sky?
The effects of "twinkling" is caused by the Earth's atmosphere.
Why some stars twinkle and why some do not?
The twinkling of the stars is caused by changes in temperature and pressure in our atmosphere. Therefore it is random, and not a meassure of the stars.
What do you mean by blue stars shiver in the distance?
This phrase likely refers to the twinkling effect observed when looking at distant stars through Earth's atmosphere. The twinkling, or shivering, of blue stars is caused by the turbulence in the atmosphere bending and scattering the starlight as it reaches our eyes.
What is the scientific name for the twinkling of stars?
groove shark did a fart under water
