Physics Waves

Question 1

What is the aim?

Answer 1

To make observations to identify the suitability of apparatus to measure frequency, wavelength and speed of waves in a ripple tank and waves in a solid and take appropriate measurements

Question 2

Independent variable

Answer 2

Frequency of waves

Question 3

Dependent variable

Answer 3

Wavelength and wave speed

Question 4

Control variables

Answer 4

Depth of water in a ripple tank, shape of ripple tank and the shape of the object creating the waves

Question 5

What is the equation that links wave speed, frequency and wavelength?

Answer 5

Wavespeed= frequency x wavelength

Question 6

Why does the student use such a low frequency on the signal generator?

Answer 6

To make sure the wavelength isnt too short to measure using a ruled

Question 7

Which of the following properties of a wave is proportional to frequency when the wavelength is kept constant?

Answer 7

Wave speed
