Wave trivia
100
What are waves?
Disturbances that transfer energy without carrying matter.
100

What is a peak?

the highest part of a transverse wave

100
What is a reflection and how can it be used to tell the depth of a lake
The bouncing back of a wave when it hits a surface through which it cannot pass. The longer it takes to bounce back, the further away the object is.
100

If a sound wave has a high amplitude, is it a quiet or loud sound?

Loud sound

100

What happens to wavelength as wave frequency increases?

Wavelength gets shorter.

200
What are mechanical waves?
The type of waves that needs a medium to transfer energy.
200

What is a wavelength?

the distance between peak to peak or trough to trough in a transverse wave or from compression to compression or rarefaction to rarefaction in a longitudinal wave.

200
At what speed do electromagnetic waves travel?
The speed of light.
200
What is a decibel?
unit for measuring loudness
200

Particles move parallel to the flow of energy in a transverse or longitudinal wave?

Longitudinal wave.

300

What is a rarefaction?

The parts where the coils or particles are spread out in a longitudinal wave

300
What is frequency?
the number of complete waves that pass a given point in a certain amount of time
300

What has a higher frequency: radio waves or gamma waves?

Gamma waves

300

What type of wave does sound travel as?

Longitudinal wave

300

What are the primary colours of light?

Red, blue and green.

400
What is a medium?
The material through which a wave travels.
400
What is Hertz?
the unit of measurement for frequency
400

What happens to light when it moves from air to to glass?

It slows down and refracts (bends towards the normal).

400
What is an echo?
a reflective sound wave
400

In what type of waves are the particles vibrated perpendicular to the flow of energy?

Transverse wave.

500
Name 4 types of electromagnetic waves?
Possible answers: Radio waves Infrared waves Visible light waves Ultra violet waves X-Rays Gamma Rays
500
What is Amplitude?
How far a particle of a medium is moved from its resting point.
500

Generally speaking, waves move quickest through which medium?

Solid.

500

Explain why no sound could be heard in space.

Sound needs a medium to travel in, and space is a vacuum (there are no particles).

500

In what circumstance would an object appear to be white in colour?

When it reflects all colours of visible light.
