Origin of the Universe

The distance between waves is called

• wavelength

• frequency

• amplitude

• volume

NGSS.HS-PS4-1

The number of waves that pass a given point in a certain amount of time

• wavelength

• frequency

• amplitute

• volume

Tags

NGSS.HS-PS4-1

As the source moves towards the observer, the frequency of the waves

• increases

• decreases

• stays the same

Tags

NGSS.HS-PS4-1

As the source moves away from the observer, the frequency of the waves

• increases

• decreases

• stays the same

NGSS.HS-PS4-1

Use the diagram to complete the question.

As the source approaches (is closer to) the observer, the frequency is

• higher

• lower

• remains the same

NGSS.HS-PS4-1

Use the dfiagram to answer the question.

As the source moves away from the observer, the wavelength

• increases

• decreases

• stays the same

NGSS.HS-PS4-1

Use the diagram to complete the question.

As the source moves away from the observer, there is a shift toward

• violet

• blue

• green

• red

The shift in the absorption lines toward red shows that the star is moving

• toward Earth

• away from Earth

• in an orbit around the sun

• in an orbit around the Earth

The Big Bang Theory states that the universe is

• expaning

• contracting

• not changing in size
