What are the two types of wave? |
The two types of wave are transverse and longitudinal |
|
|
|
What are Transverse waves? |
Transverse waves are waves were the vibrations are perpendicular to the direction of energy transfer of the wave |
|
|
|
What are longitudinal waves? |
Longitudinal waves are waves in which the vibrations are parallel to the direction of energy transfer of the wave |
|
|
|
What 3 things do all waves do? |
All waves REFRACT, REFLECT & DIFFEACT |
|
|
|
What is diffraction? |
When waves 'bend round' obstacles and spread out |
|
|
|
What two things affect how much the wave spreads out |
The narrower the gap or the longer the wavelength, the more the wave spreads out |
|
|
|
What is counted as a narrow gap in diffraction? |
When the gap is the same magnitude as the wavelength |
|
|
|
When do waves refract? |
Waves refract when they enter a different medium at an angle |
|
|
|
What is the order of wavelength of electromagnetic waves? |
|
Rock Music Is Very Useful for eXperiments with Goths |
|
|
What are radio waves used for? |
Radio waves are mainly used for communication as long wavelength waves diffract around the Earth |
|
|
|
What are microwaves used for? |
Microwaves are used for communication to and from satellites |
|
|
|
What are infrared waves used for? |
Infrared waves are used in many wireless remote controls and optical fibres |
|
|
|
What is visible light used for? |
Visible light is used for photography as cameras focus visible light onto a sensitive film or electrical receptor |
|
|
|
What parts of a sound wave are there? |
Sound waves have compressions as the particles vibrate and then move along |
|
|
|
Where do sound waves travel fastest? |
Sound waves travel fastest in solids as they are denser |
|
|
|
The bigger the amplitude the...........the sound |
The bigger the amplitude the LOUDER the sound |
|
|
|
The higher the frequency the ............ the sound |
The higher the frequency the more high pitched/SQUEAKER the sound |
|
