Q9:

Below is a picture of two waves that have different frequencies. Which of these describes the word frequency?

• AThe distance between two crests of a wave
• BThe number of times a wave goes through its cycle in a certain amount of time
• CThe tallest height a wave can travel
• DThe distance between two troughs of a wave

Q10:
