Chapters 1 + 2 Review science

Question 0

Identify and label the parts of a transverse wave

Answer 0

WAVE:
〰〰〰〰〰〰〰〰〰〰〰
The high point on the transverse wave is the crest
The low point on the transverse wave is the trough

Question 1

Describe a mechanical wave & different types of mechanical waves

Answer 1

• A wave that requires a medium to travel through *

Transverse, Longitudinal, Surface Waves

Question 2

Identify and label the parts of a longitudinal wave

Answer 2

WAVE:
➰➰➰➰
When the particles are close together it’s the compression
When the particles are far apart it’s the compression

Question 3

Identify amplitude and wave length on a transverse wave

Answer 3

Amplitude: from the rest position to the crest/trough

Wavelength: from 2 corresponding parts of a wave (crest to crest OR trough to trough)

Question 4

Know the difference between the amplitude, wavelength, frequency and speed of a wave

Answer 4

Amplitude: the height of a waves crest or trough or how compressed or rarefied

Wavelength: the distance between 2 corresponding parts of a wave

Frequency: how often a wave occurs in a given amount of time

Speed: how far a wave travels in a given amount of time

Question 5

How the amount of energy in a wave effects the amplitude

Answer 5

The more energy the wave has the higher amount the amplitude

Question 6

How wavelength effects the frequency of a wave

Answer 6

When the wavelength is short the frequency is quicker and if the wavelength is longer the frequency is shorter

Question 7

How to describe frequency in hertz

Answer 7

The unit is called Hertz (Hz)
