Question

Work out the wavelength of ultrasonic waves of frequency 10 Hz travelling at 1400 m/s.​

Answer 1

☀️ Given that: A ultrasonic wave is travelling with a frequency of 10 Hz at the 1400 m/s

      Need to find: Wavelength

Must know:

Formula for calculating wavelength  λ = v/f

Where,

• λ denotes the wavelength
• v denotes velocity
• f denotes frequency

Solution:

→ λ = v/f

→ λ = 1400/10

→ λ = 140m

⠀━━━━━━━━━━━━━━━━━━━  

• Henceforth, the wavelength of ultrasonic waves is 140m
