Question

What is the frequency of sound of wave length 5 m. and speed 340 m/s​

Answer 1

Understanding the question: This question says that we have to find out the frequency of the sound if the wavelength is 5 metres and the speed is given as 340 m/s. Let's solve this question!

Given that:

• Wavelength = 5 metres
• Velocity = 340 m/s

To calculate:

• Frequency of sound

Solution:

• Frequency of sound = 68 Hz

Using concept:

• Frequency formula

Using formula:

• Frequency = Velocity/Wavelength

Full solution:

→ Frequency = Velocity/Wavelength

→ Frequency = 340/5

→ Frequency = 68 Hz $\:$
