Ripple tank (Required Practical)

Question 1

how do you measure wavelength with a ripple tank

Answer 1

1. To measure the wavelength we place a ruler on the paper. We then freeze the image of the waves.
2. We now measure the distance between one wave and ten waves further.
3. to find one wavelength divide by 10

Question 2

what is the wave equation to work out speed

Answer 2

wave speed= frequency X wavelength

Question 3

how to find the frequency of waves

Answer 3

1. To find the frequency, we need to place a timer next to the paper and count the number of waves passing a point in 10 seconds and divide by 10
2. use a slow motion camera to record the timer and the paper to get an accurate result
