What is the amplitude of a wave?
The distance between two consecutive crests
The height from the rest position to the crest
The number of waves that pass a point in one second
The time it takes for one complete wave to pass a point
Using the Hertzsprung-Russell diagram, how are stars classified?
By their distance from Earth

In the bulge
What evidence supports the Big Bang theory as the origin of the universe?
The presence of black holes
The cosmic microwave background radiation
The existence of dark matter
The formation of stars
Compare the frequency of red light to blue light in the electromagnetic spectrum.
Red light has a higher frequency than blue light
Red light has a lower frequency than blue light
Red light and blue light have the same frequency
Frequency cannot be compared
What is the primary characteristic of an elliptical galaxy?
It has a well-defined spiral structure
It has a spherical or oval shape
It has irregular shapes with no distinct form

Describe the relationship between wavelength and frequency in a wave.
As wavelength increases, frequency increases
As wavelength increases, frequency decreases
Wavelength and frequency are unrelated
Wavelength and frequency are always equal

The cosmic microwave background radiation
The formation of new stars
What is the role of dark matter in the universe?
It emits light and heat
It interacts with electromagnetic forces
It affects the gravitational forces in galaxies (helps create them)
It is visible through telescopes
