Q

what are the oscillations for transverse and longitudinal waves?

A

In transverse waves oscillations are perpendicular (90) to the direction of energy transfer
Most waves are transverse including:
1)Electromagnetic waves
2)Ripples and waves in water
3)A wave on a string

In longitudinal waves the oscillations are parallel to the direction of energy transfer eg sound waves

Q

what is wave speed and what is the equation?

A

Wave speed is the speed at which energy is being transferred
Equation Frequency times wavelength
V=f × λ
V= wavespeed m/s
F=frequency (hz)
λ=wavelength (m)

Q

what is one important fact about waves?

A

For both ripples on a water surface and sound waves in the air it is the wave that travels and not the water or the air

Q

what is the amplitude on a wave?
what is the wavelength of a wave?

A

The amplitude of wave is the maximum displacement of a point on a wave away from it’s undisturbed position

The wavelength of a wave is the distance from a point on one wave to the equivalent point on the adjacent wave

Q

How do you work out the wavelength of a wave?
what is the symbol a wave?

A

You can measure the top of the wave (between),middle part and the bottom part
Symbol- λ is called lambda

Q

what is frequency?
what is the unit?
how do you work it out?

A

The number waves passing a point each second
Unit is hz=hertz
1 hz= 1 wave per second
Count the number of waves there are (between)

Q

what is a period?
what is the unit?
what is the equation?

A

Period is the time (in seconds) for one wave to pass a point
Unit is seconds
Equation is 1/frequency hz
