What happens at higher temperatures?

The continuous spectrum of an ideal object as a result of its temperature alone

A planet moving faster nearer the sun

A planet moves slower when farthest from the sun

The geometric arrangements among the Earth, the Sun, and another planet

When a planet is directly between Sun and the Earth

When a planet is on the opposite side of the Sun from the Earth

The energy per photon depends on __________.

How shiny the color of a planet is

Name the Electromagnetic Spectrum from lowest to highest frequency:

Which law says that the orbital period is related to the orbit's size
(P²=a³)

What does p²=a³ mean?

Where everything revolves around the Earth

Magnification is given by ratio of _______.

The amount of a Doppler Shift (blue or red) varies how?

Where planets usually move slowly to the left (eastward) relative to background stars

Where a planet seems to stop and back up for several weeks or months (westward relative to background stars)

The blurring of objects as different colors of light being refracted by different amounts causing the different colors to have diferent focal lengths

Uses sensors to determine the amount of twinkling created by atmospheric turbulence

The following are all characteristics of what?:
A pair of widely-seperated telescopes
Study the interface pattern
Reconstruct original image/no atmospheric blurring
Example: GSU CHARA Array on Mt. Wilson

The following are all characheristics of what?:

Analyze the atmospheric blurring
Adjust telescope optics to compensate
Improve resolution of detail

The following are all characheristics of what?:

electronic detectors (CCD's) turn photons into an electric current

more sensitive and easier to interpret than film; real time results

How is the GSU CHARA aray different from the Hubble Space Telescope?

What all does a telescope do?

As planets gets smaller, densities get smaller because of ______. Why?

Where all the colors of the spectrum of an approaching source are shifted toward the short wavelength of the spectrum

The change in direction as light travels from one medium to another

The smallest angle that can be resolved is set by _____.

The resolution of fine detail ideally improves with _______.

What are some disadvantages of large refractors?

Spectral lines originate in ________.

Spectral lines are analyzed to ________.

What happens in the Doppler Effect?

A theory of the overall structure and evolution of the universe

The orbits are eclipses with the sun at one focus (described by semimajor axis and eccentricity)

The time it takes a planet to make one complete orbit of the sun
