Question

A sound wave has a frequency 320 Hz and wavelength 0.25 m . How much distance will it travel in 10 s​

Answer 1

Answer:

• 800 m.

Explanation:

Given

• Frequency = 320 Hz
• Wavelength = 0.25 m
• Time period = 10 s

To find

• Distance

Solution

→ Speed of sound = Frequency × Wavelength

→ V = Fλ

• 320 × 0.25
• 80

Hence, the speed of sound is 80 m/s.

→ Speed = Distance / Time

→ Distance = Speed × Time

• 80 × 10
• 800

Hence, the distance travelled is 10 s is 800 m.
