REQUIRED PRACTICAL: WAVES ON A STRING

Question 1

How is the wave caused?

Answer 1

• the transducer vibrates

Question 2

How do you measure the wavelength of the waves accurately?

Answer 2

• measure the length of the string using a tape measure
• divide this distance by the number of waves
• this is the wavelength of 1 wave

Question 3

What is the equation which links wavelength, frequency and speed?

Answer 3

wave speed (v) = frequency (f) x wavelength (λ)
