Wave features
What do we call the bottom of a transverse wave?
Trough
What do all waves transfer?
Energy
How long is a 150cm wavelength in metres?
1.5m
Name 3 different Electromagnetic Waves
Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma
What type of EM wave can help you see broken bones
X-Rays
What name do we give the distance between two peaks on a wave
Wavelength
What type of wave is faster than a sound wave?
Light waves
A frequency of 10kHz is how much in Hz?
10,000Hz
Radio, Microwave, X, Visible, Ultraviolet, Y, Gamma.
What are the two missing waves?
Infrared and X-ray
Which EM wave has the shortest wavelength?
Gamma
The name for how many waves there are per second
Frequency
Why can we not hear anything in space?
Because space is a vacuum
A very small wave might have a wavelength of 50mm. How much is that in metres?
0.05m
Which EM wave travels the fastest?
They all have the same speed
Which EM waves do we use in TV controllers?
Infrared
What do we measure Frequency in?
Hertz (Hz)
In this wave, particles oscillate perpendicular to the direction of energy travel
Transverse
A loud sound wave has an amplitude of 2Mm. How many metres is that?
2,000,000m
Name something Light waves can do that Sound waves cannot.
Travel in space
This wave allows communication using satellites
Microwave
What name is given to sections of a longitudinal wave where particles are very spread out
Rarefaction
When two peaks meet, they add together. What do we call this?
Superposing
A high frequency gamma wave has a frequency of 80THz. How many Hertz is that?
80,000,000,000,000Hz
What is the speed of light in metres per second? (Closest guess after 3 guesses wins)
300,000,000m/s
Which EM Wave is the most ionising (1 guess each)
Gamma
