Required Practical 08.2: Waves in a solid

Question 1

How do you measure the wave length of a standing wave? (3)

• total
• number
• multiply

Answer 1

1. Measure total length of standing wave from wooden bridge to the vibration generator using a ruler.
2. Divide the total length by the number of ½ wave lengths.
3. Multiply your answer by 2

Question 2

How do you measure the wave speed of a standing wave?

• wave length
• equation

Answer 2

1. Calculate the wave length of the standing wave.
2. Use the equation: wave speed = f × λ (Read the frequency off the generator)
