Physics Flies: Wonders Of The Universe Tour

The study of science is Physics. Physics means the natural science which involves the study of things made up atoms or matter, and along with related concepts such as energy and force. The experiment is Physics because we are using heat from the sun, and transferring the heat to the oven. So heat or thermal energy is the measure of the amount of energy that is contained in a material. Heat depends on how much of the material, which would be sunlight, you have: if you have twice the amount then normal of whatever you are testing, then you have to double the amount of heat you have. “Temperature is a measure of the ability of a substance, or more generally of any living or nonliving subject, to move the energy made of heat to another living or nonliving subject.” “But we need to remember that light slows down has it goes farther from the sun, and bends toward the normal and has a shorter wavelength when it enters a higher value medium (A substance that makes it possible for the energy to move to one location to another)”. “ Also a light wave is transverse (they can be polarized).”

A red dwarf star’s HZ, for example, would be much closer to the star itself compared with that of our sun. It is also important to determine the planet’s size and mass, which is imperative in deciding whether it can sustain an atmosphere. Maintaining an atmosphere is essential for life to exist and small a planet with a small gravitational force at its surface may not be capable of retaining one. The Kepler transit data can only measure planet masses, diameters, orbital periods, and parent star types and although this information is useful for determining habitable zones, further data is required to determine true habitability. The latter can be done by studying the composition of the exoplanet’s atmosphere.

The order in which the greatest blue shift to the red shift of the five distant stars is E, D, B, C, A. The arrows in the diagram represent the speed of movement of the star, the longer the arrow the faster the movement of the star and vice versa. Furthermore, the motion of the source of light is said to be blueshifted if it is moving towards the observer, but if the source is moving away from the observer it is called redshifted (Prather p75). As a result, the star that is moving faster toward the observer will have the greatest blueshift while the star that is moving away from an observer will have the greatest redshift.

Both high- and low-mass stars respond to the depletion of hydrogen fuel in a similar manner. In order to supply the heat to oppose its own self-gravity, the star 's core again responds by shrinking. In a sort of reflex reaction, the outer regions of the star expand, causing a great increase of its radiating surface area. Although the total energy output of the star increases during this phase, the greatly enhanced surface area results in a cooling of the surface and the star takes on a redder appearance. The size and color change lead to the name of red giant for these stars. If the star is very massive, it may become what is called a red supergiant.

We can determine an object’s temperature from its thermal (or “blackbody”) spectrum by finding the wavelength at which it emits the most electromagnetic radiation.

a. Stars may appear brighter because they are burning hotter than other stars around them.

It’s called the HR diagram because it tells about the life cycles of stars. By observing and looking at the life cycles of many other stars we can evaluate the date that will tell us all different stages of evolution and growth. While discovering luminosities this helped measure how much energy a star gives off as well as it’s colour that makes categorizing pretty spot on. Because of that a Danish astronomer research combied with russells research based on their spectral types this helped figure out there life cycle of the stars. Even though two women was behind it and it should be named after them but you know how it goes.

This light is known as the spectrum emission color of an element which can also be used to identify an element as well as determine the energy that is given off. In this lab we used this information to identify three unknown substances and determine if the energy given off was high or low. In order to conduct this lab we had to take a known substance for example Copper Chloride (CuCl) and use a splint to put the substance over a bunsen burner. We then recorded the frequency, color of the flame, and the spectrum emission line by using spectroscopes, which diffracts light.

14. Different levels of brightness are due to different levels of heat, and different distances.

5. On what kind of diagram are stars plotted according to their surface temperature and luminosity?

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

Everyone has experienced warmth by sunlight. In this science fair project i will determine how the color of an object affects the amount of radiant energy absorbed.

     Stars are a marvelous wonder to many people, that is why some people spend most of their lives wondering what is “above the world so high” (Gardner 98). These people study and map the little twinkling stars in order to get a better meaning of them; they are astronomers. Great astronomers like Edwin Hubble, Immanuel Kant, and William Huggins, never stopped valuing the beauty of the stars. While they developed great astronomical principals. One astronomer who fits this mold most is, Edwin Powell Hubble. Wondering about what was

Pulsating white dwarf stars are a special subclass of white dwarfs, and they are very useful tools for studying the interiors of stars. As the interior of the white dwarf changes and oscillates, the light signal from the star will pulsate at numerous frequencies. By determining the frequencies at which the star pulsates and using these as boundary conditions in stellar models, astronomers can determine the interior properties of white dwarfs. This summer I was involved in using data from the Whole Earth Telescope and CCD images to determine the frequencies at which two different white dwarf stars pulsate.

Since the beginning of recorded civilization, stars played a huge role in religion and proved vital to routing. The invention of the telescope, the discovery of the “laws of motion” and gravity in the 17th century prompted the
