Total questions: 15
Worksheet time: 8mins
What is the unit of measurement for wave speed?
Miles per hour (mph)
Centimeters per second (cm/s)
Metres per second (m/s)
Kilometers per hour (km/h)
How fast do sound waves travel through air?
500 m/s
400 m/s
330 m/s
300 m/s
What is the wavelength of waves if 5 waves fit into a 60 m pier?
12 m
20 m
10 m
15 m
What is the formula that connects speed, frequency, and wavelength?
v = fλ
v = λ/f
v = f + λ
v = f - λ
What happens to the frequency of waves when they change speed in different materials?
It remains unchanged
It decreases
It doubles
It increases
What type of waves are sound waves classified as?
Surface waves
Longitudinal waves
Electromagnetic waves
Transverse waves
What is the relationship between frequency and period?
Frequency = Period × Wavelength
Frequency = Wavelength/Time
Frequency = 1/Period
Frequency = Period × Time
What is the speed of sound in air approximately?
150 m/s
760 m/s
330 m/s
1000 m/s
What is the effect of temperature on the speed of sound?
It has no effect
It slows down
It speeds up
It doubles the speed
What is the term for sound waves that are above the range of human hearing?
Subsonic
Hypersonic
Ultrasonic
Infrasonic
What happens to sound waves when they hit a hard surface?
They are refracted
They are diffracted
They are reflected
They are absorbed
What device measures the depth of water using sound waves?
Sonar
Radar
Oscilloscope
Microphone
What is the relationship between amplitude and energy in sound waves?
Amplitude is unrelated to sound
Higher amplitude means less energy
Amplitude has no effect on energy
Higher amplitude means more energy
What is the frequency range that the human ear can typically detect?
50 Hz to 50,000 Hz
30 Hz to 30,000 Hz
20 Hz to 20,000 Hz
10 Hz to 10,000 Hz
What is the term for the time it takes for a sound to return after being reflected?
Reflection time
Reverberation time
Sound delay
Echo time
