The image above shows a?
Longitudinal wave
Transverse wave
Mexican wave
A big wave
Using a slinky to show compressions is a good way to demonstrate...
Longitudinal waves
Transverse waves
Mexican waves
A big wave
The dashed line that runs through the middle of a transverse wave is called the (a) line
You work out the (a) by measuring the distance between the normal line and peak, or normal line and trough
Which wave has the largest volume?
A
B
C
All the same
Which wave has the lowest pitch?
A
B
C
All the same
Which wave has the highest pitch?
A
B
C
All the same
Which wave has the highest frequency?
A
B
C
All the same
Which wave has the lowest frequency?
A
B
C
All the same
Wavelength can be measured from...
Peak to peak
trough to trough
(where the wave meets the normal line to where it meets again) x 2
All of the above
The wavelength of this wave is? (remember units)
(a)
Which of the following is the wave equation?
wave speed = frequency / wavelength
frequency = wave speed x wavelength
wavelength = frequency x wave speed
wave speed = frequency x wavelength
What symbol do we use for wave speed?
S
WS
v
K
What is the unit of frequency?
Beats
Seconds
metres per second
Hertz
What is the unit symbol for Hertz
Hz
H
z
hz
Using the wave equation: wave speed = frequency x wavelength.
If a wave had a frequency of 300Hz and a wavelength of 3m, what would the speed be in m/s?
(a)
Using the wave equation wave speed = frequency x wavelength (this time you will need to re-arrange).
Calculate the wavelength if a wave has a speed of 250m/s and a frequency of 50Hz.
Remember your units
(a)
Which of these is a use of ultrasound?
Sonography - look at an unborn baby in the womb
Radar
Work out how thick an object is
all of the above
Why is using an ultrasound on an unborn baby better than using an x-ray?
Which of these are part of the electromagnetic (EM) spectrum? (you may check more than one)
radio waves
x rays
sound waves
visible light
What of the EM spectrum has the largest wavelength and lowest frequency?
Radio waves
Microwaves
Gamma waves
Trick question - a wave can't have the largest wavelength and lowest frequency
What wave of the EM spectrum has the highest frequency and shortest wavelength
Radio waves
microwaves
gamma waves
trick question
True or False! All of the waves of the EM spectrum travel at the same speed, the speed of light.
True
False
In the next few questions you must complete the spectrum.

What is meant by ionizing radiation?
Radiation that kills people
Waves that can cause electrons to detach from an atom or molecule
Waves that can reflect and refract
Waves that have entered earth's atmosphere from space
Which parts of the EM spectrum are considered to be ionizing radiation?
Radio waves and Microwaves
Visible light and Ultraviolet
X-rays and Gamma rays
All of the spectrum
Microwaves can be used for: (may tick more than 1)
Heating food
Communication
Eye Surgery
Security
One of the uses of visible light is its use in fibre (a)
In scientific terms best explain what an echo is
When waves hit a surface, for it to reflect in an ordered and uniform manner the surface must be...
rough and jagged
just rough
smooth and flat
true or false! The angle at which a wave hits a flat smooth surface is equal to the angle it reflects off that surface
true
false
The ray that travels from a source to the reflective surface, often labelled with an 'i', is called an ____________ ray.
institution
ideal
inclined
incident
When a light ray moves from air into water, does they ray bend towards the normal or away from the normal?
towards
away
If a light ray is travelling in a glass box, as it leaves the glass box and moves into air, doe the light bend towards or away from the normal line?
towards
away
What is a medium?
Psychic
A wave
A material or substance through which a wave can travel
A vacuum
Which of the following statements are true
When a wave travels from a high density medium into a low density medium the wave bends away from the normal
When a wave travels from a high density medium into a low density medium the wave bends towards the normal
When a wave travels from a low density medium into a high density medium the wave bends away from the normal
When a wave travels from a low density medium into a high density medium the wave bends towards the normal
