Waves

Question 1

What are the two types of waves and what do they do

Answer 1

Longitudinal -Particles vibrate in the same direction as the energy transfer

Transverse-Particles vibrate perpendicular to the energy transfer

Question 2

Give an example of a longitudinal and transverse wave

Answer 2

Longitudinal -Sound
Transverse-Water and Light

Question 3

What is the definition of wavelength

Answer 3

Wavelength is the distance from one wave to the same point on the next wave.

Question 4

What is the definition of frequency ,the symbol and what it’s measured in

Answer 4

Frequency is the number of waves that pass in one second and has the symbol f and is measured in Hertz (Hz)

Question 5

What is the definition of reflection

Answer 5

When a wave bounces off something

Question 6

What is the two properties of EM Spectrum

Answer 6

They travel at the speed of light
They are all transverse waves
They do not need particles to travel

Question 7

What is diffraction

Answer 7

Diffraction is when waves can bend around corners and past obstacles

Question 8

What is the period

Answer 8

The period of a wave is the length of time for one wave to go past

Question 9

List the EM spectrum in order

Answer 9

Radio,Microwave,Infrared,Visible,
Ultraviolet,X-Rays and Gamma Rays

Question 10

What is Refraction

Answer 10

The change of direction of a wave when travelled from one medium to another
