Physics Words Revision Flashcards
Transverse wave
A wave in which the vibration causing the wave is at a right angles to the direction of the energy transfer
Longitudinal wave
A wave in which the vibration causing the wave is parallel to the direction of the energy transfer ( looks like a barcode )
Amplitude
The height of the wave measured from the middle ( the undisturbed position of the water)
Wavelength
The distance from a point on 1 wave to the exact same spot on the next wave
Frequency
The number of waves produced each second. It is also the number of waves passing a point each second
Period
The time taken to produce 1 wave
Angle of refraction
The angle between the refracted ray and the normal
Echo
Reflection of sound ( double the distance of travel)
Equation for finding velocity
V=f x y
Velocity = frequency x wavelength
Velocity
Velocity = distance / time
Frequency ( equation )
Frequency = 1 / time period Hz = 1 / s
What is the symbol for frequency
Hz
Symbol for velocity
V
Symbol for wavelength
Upside down y
Dissipate
To scatter in all directions or to use waste fully . When energy has been dissipated it means we Carnt get it back . The energy has spread out and heats up the surroundings
