Question 1

What are the 2 main waves called?

Answer 1

Longitudinal waves

Transverse waves

Question 2

What direction does transverse waves go?

Answer 2

Side to side but going at a 90 angle

Question 3

What is amplitude in a wave?

Answer 3

Amplitude is the height from the wave crest

Question 4

What is frequency in a wave?

Answer 4

Frequency is the number of wave crests passing a point per one second.

Question 5

What is wavelength?

Answer 5

wavelength is the distance from one wave crest to the next wave crest.

Question 6

What is the normal humans earning frequency?

Answer 6

20Hz to 20,000Hz

Question 7

What wave is sound?

Answer 7

Sound is a longitudinal wave

Question 8

Farrier we go away in space, what happens to the red shift?

Answer 8

It gets greater

Question 9

Is red shift a transverse wave?

Answer 9

Yes

Question 10

What is red shift?

Answer 10

Increase in the wavelength in light

Question 11

What are the 3 main point about the Big Bang?

Answer 11

Single point
explosion
Universe is expanding

Question 12

Why is there red shift

Answer 12

The galaxy are moving away

Question 13

Explain why the 3 main point prove about the Big Bang theory?

Answer 13

Single point- reverse red shift galaxies started at single point
Exploring- further galaxies more red shift = moving faster
Universe exploring- all galaxies show red shift, all moving away from each other

Question 14

What is CMBR

Answer 14

Cosmic microwave background radiation
