Use the grids below to draw the following waves. Be sure to label the y-axis to indicate the
measurement scale.
a.
A wave with an amplitude of
1 cm and a wavelength of 2 cm
b.
23.2
A wave with an amplitude of
1.5 cm and a wavelength of
3 cm
3.
A water wave has a frequency of 2 hertz and a wavelength of 5 meters. Calculate its speed.
4.
A wave has a speed of 50 m/s and a frequency of 10 Hz. Calculate its wavelength.
5.
A wave has a speed of 30 m/s and a wavelength of 3 meters. Calculate its frequency.
6.
A wave has a period of 2 seconds and a wavelength of 4 meters.Calculate its frequency and speed.
Note: Recall that the frequency of a wave equals 1/period and the period of a wave equals 1/frequency.
7.
A sound wave travels at 330 m/s and has a wavelength of 2 meters. Calculate its frequency and period.
8.
The frequency of wave A is 250 hertz and the wavelength is 30 centimeters. The frequency of wave B is
260 hertz and the wavelength is 25 centimeters. Which is the faster wave?
9.
The period of a wave is equal to the time it takes for one wavelength to pass by a fixed point. You stand on a
pier watching water waves and see 10 wavelengths pass by in a time of 40 seconds.
a.
What is the period of the water waves?
b.
What is the frequency of the water waves?
c.
If the wavelength is 3 meters, what is the
