Question 1

Transverse wave:
direction of movement?
direction of energy transfer?

Answer 1

Movement/oscillation=up and down

Energy transfer= sideways

Question 2

Longitudinal wave
direction of movement?
direction of energy transfer?

Answer 2

Movement/oscillation=side to side

Energy transfer=side to side

Question 3

Define frequency of waves

Answer 3

The number of waves per second

Question 4

Transverse waves
length?
frequency?

Answer 4

Length= high/long wavelength 
Frequency= low

Question 5

Longitudinal wave
length?
frequency?

Answer 5

Length= low wavelength
Frequency= high frequency

Question 6

Time (frequency) equation

Answer 6

Time= 1/frequency

Question 7

How to find the speed of a wave

Answer 7

Use a ripple tank

Question 8

Wave speed equation

Answer 8

Wave speed= frequency x wavelength

V= fλ

Question 9

Electromagnetic spectrum order/uses?

and energy level/frequency/wavelength?

Answer 9

Radio waves- radio communication
Microwave- phones
Infrared- remote control
Visible light- transmitting data
Ultra violet- detecting fake money
X-ray- broken bones
Gamma ray- treating cancers

Question 10

Refraction

Examples

Answer 10

Happens when a wave passes from one medium into another medium. and it will change direction because the wave changes speed, and different parts of the wave change speed at different points.

Question 11

Radiation
Good absorbers?
Good emitters?
Good reflectors?

Answer 11

Absorbers= dark surfaces and matt surfaces

Emitters= dark surfaces, matt surfaces

Reflectors= shiny
