The doppler and Red shift effect

Question 1

What happens to the wavelength and frequency when a car is moving towards you?

Answer 1

The wavelength becomes shorter and the frequency becomes a higher pitch

Question 2

What happens to the wavelength and frequency when the car is moving away from you?

Answer 2

The wavelength becomes longer and the frequency becomes a lower pitch.

Question 3

What colour is given to a longer wavelength?

Answer 3

Red

Question 4

What colour is given to a shorter wavelength?

Answer 4

Blue

Question 5

What will a star in the sky look if it is moving away from us?

Answer 5

Red

Question 6

List to pieces of evidence to support the Big Bang theory?

Answer 6

1) CMBR- Cosmetic Microwave background radiation

2) Galaxies are moving away from us

Question 7

What is red shift?

Answer 7

The increase of a wavelength of light as a galaxy moves further away

Question 8

What does red shift tell us about galaxies?

Answer 8

The further away the galaxy the bigger and faster the redshift

Question 9

What is CMBR?

Answer 9

A form of electromagnetic radiation filling the universe

Question 10

What is the “big bang theory”

Answer 10

Universe began from a very small initial point

Question 11

How does red shift support evidence for the big bang theory?

Answer 11

An expanding universe must have originated from an initial point
