Plunger Lab Name: ______________________________ Use the website for this activity. It is also located under Mr. Gorden’s classroom page on his website. Plunger Speed Plunger Size Amplitude (cm) Wavelength (cm) Frequency (waves per second) SLOW SMALL 1 cm 14 cm .88 Hz SLOW MEDIUM 2 cm 15 cm .8 Hz SLOW LARGE 3 cm 15 cm .81 Hz FAST SMALL 1 cm 6.5 cm 1.3 Hz FAST MEDIUM 2 cm 6 cm 1.3 Hz FAST LARGE 3 cm 5.8 cm 1.3 Hz SUPER FAST SMALL 1 cm 3.2 cm 2.2 Hz SUPER FAST MEDIUM 2 cm 3 cm 2.5 Hz SUPER FAST LARGE 3 cm 3 cm 2.35 Hz 1. How does the size of the ball on the plunger affect the amplitude of the waves? As the size of the ball increase so does the amplitude of the waves. 2. What affect, if any, does increasing the speed of the plunger have on the frequency of the waves? As the speed of the plunger increases so does the frequency of the waves. 3. What affect, if any does increasing the speed of the plunger have on the WAVELENGTH of the waves? As the speed of the plunger increases so does the frequency of the waves. 4. What is the relationship between the frequency and the wavelength of a wave? The higher the frequency, the smaller the wavelength. The smaller the frequency, the larger the wavelength. 5. What effect, in any, does frequency have on the amplitude of a wave? The frequency has no effect on the amplitude of the wave as the amplitude did not change from slow, fast to superfast speed. 6. What relationship exists between the amplitude of a wave and amount of disturbance in the water? As the amplitude becomes higher the disturbance becomes greater.
