Question

One way you can change the sound of something is to increase or decrease its frequency. Which of the graphs below shows how Graph 1 would change if you increased only the frequency of the wave?

Graph A
Graph B
Graph C

Answer 1

C

Step-by-step explanation:

frequency is the number of wave-crests that pass a fixed point per second. Graph C shows a higher frequency wave (amplitude is the same as Graph 1).
