light
the type of spectrum radiated from this source (picture)
what is absorption spectrum?
an array of radio antennas that are used in astronomical observations simultaneously to simulate a discretely-sampled single telescope of very large aperture.
What is interferometer array?
the first scientist realize that the laws of motion on Earth also applied to celestial objects
Who is Newton
Most modern astronomy detectors using charge-coupled device (CCD). It is based on a physics effect discovered by Einstein.
what is photoelectric effect?
two or more types of atoms that have the same atomic number and position in the periodic table and that differ in nucleon numbers
What is isotope?
The waveband we emit
what is infrared
an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.
what is doppler shift?
when a skater is spinning slowly with her arms and legs out wide and then as soon as she pulls her arms in, the speed of her spinning increases significantly. (picture). This is because
What is the conservation of angular momentum?
the ability of a telescope to distinguish small details of an object
what is angular resolution?
the equation expresses that mass is a form of potential energy
What is E=mc2?
the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature.
what is Wien's law?
the type of spectrum emitted by a hot solid
what is continuum spectrum?
energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another
What is the conservation of energy?
A telescope's diameter tells us
what is collecting area?
a measure of the total kinetic energy of all the particles in a substance. It therefore depends both on temperature AND density
What is thermal energy?
The same speed gamma ray, X-ray, and radio travel
what is speed of light?
the wavelength can only be accessible to space telescopes and has the shortest wavelength
what is gamma ray?
A ball was thrown into the air. When it reaches the highest point, this type of energy is maximized. (picture)
what is the gravitational potential energy
a technology used to improve the performance of optical systems by reducing the effect of incoming wavefront distortions by deforming a mirror in order to compensate for the distortion.
what is adaptive optics ?
An astrophysical object's temperature, chemical composition, and velocity relative to us can be obtained through ...
