Question | Answer |
What happens when you blow up the balloon with dots on it? | they expand and increase in size |
What happens to the dots as you let some air out of the balloon? | Decrease in size (Contraction) |
Name the three theories of creating the universe | Oscillating Universe, Big Bang, and Steady State theory |
Oscillating Universe | Theory that explains how the universe was created with on/off cycle of expansion and compression |
Big Bang | present day theory explaining that the universe was created in one single point and exploded outward. |
Steady State | Theory explaining the universe began with no beginning or end and the universe doesn't change! |
Heliocentric theory | Copernicus thought universe revolved around the Sun |
Geocentric Theory | Aristotle thought universe revolved around the Earth |
ROY G BIV | red orange yellow green blue indigo violet |
Electromagnetic waves | Radio Microwave infrared visible light UV x-ray gamma |
Which EM wave allows the rainbow to show through a prism? | Visible light |
Red Shift | Increase in wavelength(Red side of spectrum/rainbow) |
Blue Shift | Decrease in in wavelength (blue side of spectrum/rainbow) |
Shift | Wave movement |
High pitch | higher frequency, shorter wavelength |
Low pitch | Lower frequency, longer wavelength |
Wave energy | Light/sound |
Spectral/absorption lines | dark lines that are unique to each element that makes up a star |
Refraction | Light is bent through a prism |
Blue shift direction | Coming toward us |
Red shift direction | going away from us |
On a spectrum what would the wavelength of orange look like compared to violet? | Larger wavelength |
Red side of spectrum | Large wavelength |
Violet side of spectrum | Small wavelength |
Name three categories of galaxies | Spiral Elliptical Irregular |
How do you remember the three types of galaxies? | I Enjoy Soup (I.E.S.) |
Spiral Galaxies | pinwheel/arms |
Elliptical Galaxies | flattened ball/no new stars can form(bright middle) *Most Common |
Irregular Galaxies | not elliptical/spiral *Rare |
Analyze whether or not a siren coming toward us has a high frequency of waves. | yes, it does. toward us = blue shift = short wave lengths = high frequency |
Which shift does a meteor have coming toward Earth? | Toward us = Blue shift |
galaxy | group of stars/gas/dust being held together by gravity |
Light year | Distance light travels per year 6trillion miles per year |
Hubble's Law | 1929 (Discovered further away galaxy is, the faster it travels) |
Do YOU KNOW SCIENTIFIC NOTATION? | YES (YOU BETTER) |
