30s - Q3
Which of the following statements are true?
Energy and wavelength are proportional.
Wavelength and frequency are not related.
Frequency is proportional to wavelength.
Wavelength is inversely proportional to frequency.
30s - Q4
Which statement below best describes why astronomers study the electromagnetic spectrum?
We use the energy emitted from celestial objects to determine the materials from which they are made.
We can see all of the electromagnetic spectrum so it’s an easy way to classify celestial objects.
The electromagnetic spectrum is easily detected and captured with technology and this enables us to travel to space more efficiently.
We use the electromagnetic spectrum for energy sources on earth.

The apparent shift in wavelength of light or sound emitted by an object when viewed by an observer is know as:
Doppler Effect
Hubble's Law
The Big Bang Theory
Red Shift
30s - Q6
The apparent shift of visible light to longer wavelengths observed in distant galaxies is known as:
Red shift
Hubble's Law
The Doppler Effect

30s - Q7
Explains that all galaxies are moving away and that further galaxies are moving faster than nearer galaxies
The Doppler Effect
Big Bang Theory
Red Shift
Hubble's Law
30s - Q8
The range of electromagnetic spectrum from approximately 400 nm-700 nm
Visible Light
Infrared Light
Microwaves
Ultraviolet Light
30s - Q9
Astronomers use hydrogen gas to determine the rate of speed of distant galaxies. The expected baseline peak for hydrogen-alpha is 660 nm. Scientists observe a galaxy where the hydrogen alpha is at 700 nm. The speed of light is 299,800,000 m/s. Which of the following is approximately the speed of the galaxy?
-17,000,000 m/s
-18,000,000 m/s
17,000,000 m/s
18,000,000 m/s
