Which elements are most

abundant in the visible

universe?

• Hydrogen and Carbon

• Carbon and Helium

What is the Doppler Effect?

• A change in frequency due to the relative motion of a wave source and an observer

• When a wave overlaps with another wave

• When a wave bounces off of another object

• When a wave bends due to traveling through a different medium

Which description is considered most accurate regarding what actually happened during the Big Bang?

• Two galaxies collided causing an immense explosion as stars crashed into one another

• All of what would become the universe was concentrated in a single small point, or singularity, which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.

• All matter emerged from a massive black hole at the center of the universe.

• Parts of the sun were ripped off by massive internal explosions and were thrown into space where they cooled to become other things, like plants, comets, and other galaxies.

Why do red-shifted light spectrums from neighboring galaxies  indicate the universe is expanding?

• Red light has the longest wavelength on the visible light spectrum
• Red light has both long and short wavelengths on the visible light spectrum
• Red light has neither long, not short wavelengths on the visible light spectrum
