Science collecting data practice Flashcards
Spreads light into different wavelengths
spectroscope
main component is a ______ of a spectroscope
prism
a spectroscope shows each part of a __________
spectrum
Composition:
each element has a _______________ _____________
spectroscopic fingerprint
(how light interacts with the element)
can determine a star’s _________based on the creation of it
age
Stars work by converting ________ into ______
mass, energy
most stars are made of
Hydrogen & Helium
The more helium and hydrogen the _______ the star is
younger
The less hydrogen & Helium there is the __________ the star is.
older
This is due to nuclear fusion
elements fuse into each other (not exactly but sort of gain energy!!!!!!!)
the younger stars:
low energy and ________ waves
radio
the older stars:
higher energy ________________
gamma, x-rays, and ultraviolet waves
The highest energy event
star exploding
gamma rays are detected
supernova
non moving light
unshifted
light moving away
redshift
light moving towards
blueshift
larger planets cause stars to ____ because of their gravitational pull on each other. Devices are created to detect these wobbling stars which results in the finding of a new star.
wobble
the method/device used for detecting wobbling stars
astrometry
spectroscopes detect changes in the __________ _________
doppler effect
the wobble of stars
radial velocity
exoplanets are planets that orbit around a star other than the ____
sun
when a planet moves between us and a star the light emitted from the star dips or decreases. this helps us determine the size & mass of a planet using ___________ __________
transit photometry
how (bright) and object looks form Earth
apparent magnitude
a photometer measures apparent magnitude using the ______________ scale
Hipparchus
