QUESTIONS LIST:

• resolution: this is the ability to separate two objects that are very close together
• blue shift: this is the color light shifts to as things move towards earth
• reflecting: this kind of telescope uses a mirror to reflect light to a focus
• doppler: the apparent change in the frequency of a way as it moves towards or away from you
• redshift: this is the color light shifts to as things move away from earth
• refracting: this kind of telescope uses a lens to bend light into a focus
• objective: this is the part of a telescope that acts like the “bucket” to collect light
• atmospheric: _ refraction is why stars twinkle light bends and moves as it travels through our atmosphere
• electromagnetic: the _ spectrum is how we observe the known universe
• chromatic: _ aberration is a problem with refracting telescopes because different colors of light at different distances behind the lens
• telescope: these act as light “buckets” that funnel light into a focus (increasing resolution)
