amazing reason and facts.
1) Sun is yellow ?
The Sun appears yellow to us when we look up at it from the surface of the Earth. This is because of the way our atmosphere interacts with the light that the Sun emits. The light from the Sun is actually made up of all the colors of the rainbow, which together combine to form white light. However, when this light enters the Earth’s atmosphere, it gets scattered in different directions by the air molecules and small particles present in the atmosphere. This scattering affects the colors of the light differently.
Shorter wavelengths of light, like blue and violet, scatter more than longer wavelengths like red and yellow. Because of this, the blue and violet light gets scattered out of the direct path from the Sun to our eyes, making the Sun itself appear less blue. This is also the reason why the sky looks blue during the day. The scattering causes the remaining light that comes directly from the Sun to be dominated by the longer wavelengths, such as yellow, orange, and red. As a result, when we look at the Sun, it often appears yellow to us.
Thus, while the Sun itself emits white light, the scattering effects of our atmosphere cause it to appear yellow from the Earth’s surface.
2) why is gas added to the smell ?
Adding a smell to natural gas is crucial for safety reasons. Natural gas itself is odorless, which poses a significant risk because leaks can go undetected. To mitigate this danger, gas companies add a chemical called mercaptan to the gas. Mercaptan has a strong, distinctive odor, often compared to the smell of rotten eggs.
The purpose of adding this smell is to make it easy for people to detect gas leaks quickly. If there’s a gas leak, the strong smell alerts people immediately, allowing them to take action, such as evacuating the area and contacting emergency services, before the gas concentration reaches dangerous levels. This early detection is vital in preventing potential explosions, fires, or asphyxiation, all of which can result from undetected gas leaks.
3) when the moon is directly overhead you will weigh slightly less.
Here’s why: the moon’s gravitational pull creates tidal forces on Earth, causing a slight distortion in the planet’s shape. When the moon is overhead or underfoot, it pulls you slightly upwards, counteracting a small portion of Earth’s gravitational pull. As a result, your weight can decrease by a tiny amount, typically less than 0.5% of your total weight. This effect is so subtle that it’s generally only measurable with precise instruments.
