Question: If a wave has a speed of 300 m/s and a frequency of 150 Hz, what is its wavelength? (2023)

Options:

Correct Answer: 2 m

Exam Year: 2023

Solution:

Using the wave equation v = fλ, we can rearrange it to find λ = v/f. Thus, λ = 300 m/s / 150 Hz = 2 m.

If a wave has a speed of 300 m/s and a frequency of 150 Hz, what is its wavelength? (2023)

If a wave has a speed of 300 m/s and a frequency of 150 Hz, what is its wavelength? (2023)

Step 1: Understand the wave equation, which is v = fλ, where v is the speed of the wave, f is the frequency, and λ (lambda) is the wavelength.
Step 2: Rearrange the equation to solve for wavelength (λ). This gives us λ = v / f.
Step 3: Plug in the values: speed (v) is 300 m/s and frequency (f) is 150 Hz.
Step 4: Calculate the wavelength: λ = 300 m/s / 150 Hz.
Step 5: Perform the division: 300 divided by 150 equals 2.
Step 6: Conclude that the wavelength (λ) is 2 meters.

Wave Equation – The relationship between wave speed (v), frequency (f), and wavelength (λ) is given by the equation v = fλ.
