Astronomy 101 Second Midterm Exam Prep

A previous Astronomy 101 midterm exam provided to help students prepare for the actual exam.

The process of acquiring knowledge or skills.

The act of assessing knowledge or skills.

Provides the material relevant to the midterm exam.

A guide for studying for any midterm, containing general study strategies.

A form used to answer multiple-choice questions on exams.

The specific textbook section, reading material or slides referenced from the course in questions on the exam.

Method for preparing and reviewing concepts.

Separating white light into its component colors by refraction through a prism.

Primarily hydrogen, helium, and lithium.

Parallax method.

Separation of light into its component colors due to differences in refraction.

The apparent shift in the position of a nearby object against a distant background.

A test on specific astronomy topics.

A document for marking multiple choice answers during an exam.

A document containing the exam questions, often associated with written response answers.

Neutrinos are elementary particles that hardly ever collide with other particles.

Neutrinos come in three varieties (or flavors).

A stage in a star's life cycle where it primarily fuses hydrogen into helium in its core.

High-mass stars fuse elements up to iron in their cores before going supernova.

Planetary nebulae emit light through their gases causing a distinctive emission spectrum.

The point where two stars in a binary system balance each other out.

As the universe expands, the proportion of heavy elements (with more than 1 proton) will likely decrease.

Planetary nebulae are primarily composed of gas ejected from a dying low-mass star.

The immense gravitational pull at the surface of Sirius B, a white dwarf, compared to Earth, is due to its extremely small radius and large mass.

High-mass stars produce white dwarfs and neutron stars, and, if large enough, black holes, at their end-of-life, through explosions and subsequent collapse.

Observing a hot, low-density gas in the Orion Nebula reveals an emission spectrum, not a continuous spectrum.

Red light has a lower frequency than blue light.

The Sun's composition differs significantly from Earth's, and isn’t mainly composed of iron and oxygen.

Neutron stars spin rapidly after their birth due to the conservation of angular momentum during gravitational collapse.

A nova explosion in a white dwarf is triggered by a surge in hydrogen fusion on the star's surface, a thermonuclear runaway.

Hydrostatic equilibrium in a star is the balance between gravity pulling inward and outward pressure from nuclear fusion.

The balance between the positive nucleus and negative electrons in an atom.

The theoretical lowest possible temperature, where there is no thermal energy.

When gravity and pressure forces in a star precisely cancel to maintain its shape.

Increasing the "tapping rate" or force of wave creation increases the wave speed in a medium.

Electron shifts between energy levels, emitting or absorbing photons.

Most of an atom's mass lies within its nucleus.

Fusion reactions occur throughout the Sun's core.

Hot opaque source produces a continuous spectrum of light.
