Questions & Step-by-Step Solutions
A wave has a frequency of 50 Hz and a speed of 340 m/s. What is its wavelength? (2021)
Steps
Concepts
Step 1: Identify the formula for wavelength, which is λ = v / f.
Step 2: Identify the values given in the question: speed (v) = 340 m/s and frequency (f) = 50 Hz.
Step 3: Substitute the values into the formula: λ = 340 m/s / 50 Hz.
Step 4: Perform the division: 340 divided by 50 equals 6.8.
Step 5: Conclude that the wavelength (λ) is 6.8 meters.
Wave Properties
– Understanding the relationship between wave speed, frequency, and wavelength.
Formula Application
– Applying the formula λ = v/f to calculate wavelength from given speed and frequency.
