What are CMEs?  - large scale eruptions of plasma and magnetic field lines from the sun’s corona., What are prominences? - a large bright feature extending outward from the sun surface., what are solar flares? - sudden intense releases of energy in the sun’s atmosphere and often associated with sunspots., what are the layers of the sun? - core, radiative zone, convection zone, photosphere, chromosphere, and corona., which layer of the sun can we see? - photosphere., what does the sunspot look like and why is it important? - a sunspot looks like a dark spot on the sun. It is important because it shows areas of strong magnetic activity., how long is the solar cycle? - 11 years, why might humans want to keep track of the solar cycle? - Because it can affect earths technology and climate, compare and contrast large and low/medium mass stars and their life cycles. - /medium mass stars like the sun live for billions of years and become white dwarfs. Large mass stars live for only millions of years and in in a supernova, becoming neutron star or a black hole. Both types of stars start by fusing hydrogen into helium in their core., how do stars produce energy? - stars produce energy by fusing light elements into heavier elements in their cores, when do stars stop producing energy? - they stopped producing energy when they run out of fuel or fusion., what are two ways stars contributed to the creation and spread of elements throughout the universe? - fusion: stars make heavier elements in their core. Super nova: exploding star scatter all elements into space., what color stars are the hottest? - blue stars, what makes ionizing radiation dangerous? - ionizing radiation is dangerous because it can damage DNA cells., order the following colors from lowest frequency to highest frequency.  - blue green orange red violet yellow., a laser is striking a sheet of polished metal and an incidence angle of 45°. What is the angle of reflection? - 45°, which of the following radiations are ionizing: infrared microwaves visible light ultraviolet light x-rays Game Rays? - ultraviolet light, x-rays, gamma rays are ionizing radiation., these two waves produce which kind of interference? - these two waves produce constructive interference., if both ways individually have amplitude of 2 m what will the amplitude be after interference? Both of these waves will accumulate a total amplitude of four because if two waves have a positive inference you add them together. - combined amplitude will be 4 meters, the blue wave has an amplitude of one in the red wave has an amplitude of two what will their combine amplitude be at points A, B, and C? - A-1, B -3, C -1, what three qualities change the angle of refraction for light? - the angle of refraction changes based on the angle of INCIDENCE and the refractive indices of two materials., during the double slit experiment, two slits are cut into a box in light is shown through the slits. On the opposite side of the box, the following pattern is produced. This is an example of which of the following properties of light? - interference, how does the wavelength of UV light compare to the wavelength of infrared light? - UV light had a shorter wavelength than infrared light., how does the frequency of UV light compared to the frequency of infrared light? - UV light has a higher frequency than infrared light., how does the energy of UV light compared to the energy of infrared light? - UV light has a higher energy than infrared light., how does the speed of UV light compared to the speed of infrared light? - UV light and infrared light full travel at the same speed in a vacuum.,
