What does a wave transfer?
Charge
Particles
Energy
Electrons
What are the two main types of wave?
Hello and goodbye
Water and radio
Transverse and longitudinal
Electromagnetic and light
Which of these is a longitudinal wave?
Sound
Ripples on a pond
X-rays
Ultra-violet
What is the top part of a transverse wave called?
The amplitude
The maximum
The peak
The frequency
What do you call the distance from one peak to the next?
The amplitude
The frequency
The volume
The wavelength
The frequency of any wave is the...
Number of waves that pass a point per minute
Number of waves that pass a point per hour
Number of waves that pass a point per day
Number of waves that pass a point per second
What happens when light waves hit a flat shiny surface?
They get absorbed
They are refracted
They are scattered
They are reflected
What happens to light rays when they hit an uneven reflective material like a piece of white paper?
They are reflected
They get absorbed
They are refracted
They are scattered
What do you call it when two travelling waves peaks meet, creating a larger peak?
Wave addition
Superposition
Destructive interference
Maximisation
What would happen if a peak travelling right, met a trough, with an equal amplitude travelling left?
The two waves would add to make a peak,double the original size
Nothing - there would be no effect
The waves would totally cancel each other out where they crossed over
The waves would reflect off each other
What is the unit of frequency?
Hertz, Hz
Amperes, A
Decibels, dB
Metres, m
What is the highest frequency, on average that a human ear can detect?
20 Hz
200 Hz
2,000 Hz
20,000 Hz
On average, what is the lowest pitch that a human ear can detect?
20,000 Hz
2,000 Hz
200 Hz
20 Hz
What is the approximate speed of sound in air?
34 m/s
340 m/s
3,400 m/s
34,000 m/s
What causes sound waves?
Nuclear reactions
Expansion due to heating
Vibrations
Constant motion
What part of your body picks up the sound waves?
The ear drum
The ear tambourine
The ear harp
The ear piano
A firework makes a loud bang. The sound wave travels at 340m/s to a large barn wall, where it reflects back. If the sound is heard 4.0 seconds after the firework, how far away is the barn?
170 m
340 m
510 m
680 m
Which device can detect sound waves and create an electrical signal?
A loudspeaker
A transistor
A microphone
A signal generator
Why can't this bell be heard?
The glass cannot carry sound as it is a solid
The bell makes a frequency which reflects off glass
There is no air in the jar so the bell does not vibrate
There is a vacuum in the jar and sound waves require particles to travel through
What do you call sounds that have a higher frequency than humans can hear?
Supersonic
Subsonic
Megasound
Ultrasound
