When comparing a star's brightness from Earth, it will always appear dimmer than the Sun. This is due in large part to Earth's close proximity to the Sun. Comparing the sun's brightness to Capella's from Earth is unfair because Capella is actually made up of four separate stars. The two yellow giants that make up Capella are quite similar to the Sun. All three stars are yellow giants and give off a similar color of light.
This phenomenon also makes submerged objects, such as fish look closer to the surface than they actually are. Another common example is a rainbow, where sunlight is refracted by raindrops. Sunlight consists of a mixture of different wavelengths, or colors, of light, with blue, for example, having a shorter wavelength than red. When this light passes through raindrops, the shorter wavelengths are bent more than the longer ones, splitting the light into its different colors. Reflection Pretty much everything you see could be considered reflection.
Chapter 14 1. Radio galaxies have sources of unusually strong radio waves emitted on either side of the galaxy and active galaxies are spirals with small, highly luminous cores like Seyfert galaxies, they also have nuclei that are produced by matter plunging into super-massive black holes. 6. By observing the velocity of the stars that orbit the black hole or by the rotational speed of its accretion disk. 10.
Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
The black shirt would also fade over time because the suns rays would eat up the shirt. #2 Question: Which method of heat transfer describes vertical circulation of a fluid as in Hadley Cell? Correct Answer: C) My Answer: A) Why it’s Wrong: Convection, Because of the circulation in the Hadley cell, two pressure belts are created. The first is a belt of semi permanent high pressure that results from the sinking air at 30°. This belt of high pressure is called the subtropical ridge.
As the drops are being added, a distinct yellow color can be observed where the drops were landing in the solution. The solution then turned blue-green and very cloudy when about 50 drops of NH3 were added. A distinct dark blue color was evident where the drops were landing in the solution. Also, there was an emission of gas while the NH3 was being added. Another change of color and clarity is evident when 15.0mL of H2SO4 was added to the
The formula excludes the absorbance of the “yellow” solution because almost all of the bromothymol blue is in the HBB form in the acidic “yellow” solution, resulting in the yellow color and making its absorbance at 616 nm almost 0, or negligible. The formula uses the absorbance of the “blue” solution because its λmax is 614.9nm, which is very close to 616nm.This means that in the “blue” solution, most of the bromothymol blue is in the form BB-, displaying a blue color that absorbs the light at 616 nm, thus resulting in a higher recorded absorbance. Below are the recorded absorbance values at 616
Then J went back to a white cloud reaction. K went to a light blue reaction but was still super liquid like. Last L was also a light blue liquid that you could see through
Spectra can tell us what makes up a star just by analyzing it. The rainbow isn’t the only thing that makes up the star spectra. If you had the ability to look into the light that comes after the color red, you will encounter the infrared light (it is the heat felt on the skin) which eventually merges into the radio section of the spectrum. On the other side of the rainbow, next to violet is a small portion called the ultra violet, which gives us sunburns and tans. You would then find the section of x-ray radiation then the deadly gamma rays.
The sky has a gradual tone from dark to light starting from the top of the image to where it meets the horizon which shows that the image was taken during a clear blue sky because of the brightness of the image. The glare of the light which reflects off the bodies of the male and female portrayed in Dupain’s Bondi image is from the sun which is located behind Dupain while he took the image. The sun’s location can be determined by the glare and the shadows which pop up on the left hand sides of their
