Question
The picture below shows sound waves in different colors. Pick the color of the sound wave which is of the highest frequency.
- Purple
- Blue
- Red
- Yellow
Hint:
The maximum number of cycles of waves are present in purple
The correct answer is: Purple
- The total number of waves produced in one second is called the frequency of the wave.
- In the given sound waves, frequency is minimum for red and maximum for purple.
- So, the correct option is a.
