The EM Spectrum 1
The waves with the lowest frequency (largest wavelength)
What are radio waves?
This is what light behaves like
What are waves?
When all colors of light are combined into one, it creates this color of light
What is white light?
The age of the universe/time since the Big Bang
What is 13.8 billion?
The frequency of waves does this when moving away from the observer
What is stretching?
The section of the EM spectrum we can see
What is visible light?
All waves on the EM spectrum go this speed
What is the speed of light?
Name 2 things measuring and collecting date of stars can tell us (4 possible answers, name 2)
What is temperature, elements, density, or motion?
The effect of light moving away from us
What is redshift?
The Doppler Effect applies to these two types of waves
What are sound and light waves?
The waves with the highest frequency (shortest wavelength)
What are gamma rays?
These particles interact with electrons to create visible light
What are photons?
This tool is used to measure the luminosity and density of colors in stars
The background noise found to be produced by the Big Bang
What is cosmic microwave background radiation?
The Doppler Effect can change this in sound waves
What is pitch?
These waves are used in medical imaging
What are x-rays?
These waves are most often used for thermal imaging
What is infrared?
When stars travel away from us, light does this to show us
What is redshift?
The process in which new atoms formed after the Big Bang
What is nucleosynthesis?
These are the 3 types of UV radiation (UV rays)
UV-A, UV-B, and UV-C
These 2 types of rays are radioactive and can be extremely dangerous
What are x-rays and gamma rays?
After analyzing spectral fingerprints, we can learn more about this measure according to the line thickness
What is density?
300,000 years after the Big Bang, these two atoms were the first to be formed
What is hydrogen and helium? (H and He)
