Lesson 3

Question 1

When two waves meet, they pass through each other and keep moving. When they move through each other the amplitudes of the waves are affected. This is known as..

Answer 1

Wave Interference

Question 2

What is it called when two waves occupy the same space at the same time?

Answer 2

Superposition

Question 3

What happens when waves are super imposed?

Answer 3

The medium will take on a sort of combined shape

Question 4

When two waves are superimposed the amplitude of the resulting wave is

Answer 4

The algebraic sum of the amplitudes of the the two waves

Question 5

Crests are _______ amplitudes. Troughs are _________ amplitudes.

Answer 5

Positive and negative

Question 6

What is constructive interference

Answer 6

Two waves superimposed that result in a wave with a larger amplitude than the original waves. Generally this happens when two crests interfere or two troughs interfere

Question 7

Destructive interference is

Answer 7

Two waves superimposed in a wave with a smaller amplitude than the original waves. Generally happens when troughs interfere with crests

Question 8

What takes place after interference

Answer 8

Waves separate and continue unchanged by the event

Question 9

What is a resultant wave

Answer 9

The total wave that results when two waves overlap and interfere
