Waves cause a disturbance of the medium through which they travel. This allows them to carry energy. The quantity of energy carried relates to the amplitude of the wave.
How is the frequency of a wave best described?
The number of waves per second
The number of waves per minute
The number of waves per hour
If the frequency of a wave is , what is the period of the wave?
What is the amplitude of a wave that is from peak to trough?
How is the speed of a wave defined?
As the distance travelled by the wave each second
As the distance travelled by the wave in one period
As the number of waves produced in one second
If the period of wave is , what is the frequency of the wave?
What is the wavelength of the wave?
Which of the following is a longitudinal wave?
If a student sees the flash of lightning strike and then hears the thunder six seconds later, how far away is the storm?
If an ultrasound pulse travels a total distance of 6 cm (0.06 m) to and from an organ and takes 40µs ( ), what is the speed of sound in the tissue?
1500 m s-1
150,000 m s-1
240 m s-1
If a water wave has a wavelength of and a frequency of , what is the speed of the water wave?
0.75 m s-1
12 m s-1
0.08 m s-1
If a sound wave in air has a frequency of , what is the wavelength of the wave?
What is the wavelength of a radio wave of frequency 89 MHz?
A streetlamp can emit a light of wavelength . What is the frequency of this light?
If the distance to a satellite is , how long does it take a signal to get from the transmitting station to a receiving station back on Earth? Be careful there are two points to watch for.
What is diffraction?
A wave changing direction through a substance
A wave changing direction going around an object
A wave changing direction by bouncing off an object
Which of the following radio signals will reach a village in the bottom of a valley best?
Short wave radio signal
Long wave radio signal
Medium wave radio signal
