Question: A wave travels at a speed of 300 m/s and has a frequency of 150 Hz. What is its wavelength?

Options:

Correct Answer: 1.5 m

Solution:

The wavelength λ can be calculated using the formula v = fλ. Thus, λ = v/f = 300 m/s / 150 Hz = 2 m.

A wave travels at a speed of 300 m/s and has a frequency of 150 Hz. What is its wavelength?

A wave travels at a speed of 300 m/s and has a frequency of 150 Hz. What is its wavelength?

Step 1: Identify the speed of the wave (v). In this case, v = 300 m/s.
Step 2: Identify the frequency of the wave (f). Here, f = 150 Hz.
Step 3: Use the formula for wave speed, which is v = f * λ, where λ is the wavelength.
Step 4: Rearrange the formula to solve for wavelength (λ). This gives us λ = v / f.
Step 5: Substitute the values into the formula: λ = 300 m/s / 150 Hz.
Step 6: Perform the division: 300 divided by 150 equals 2.
Step 7: Conclude that the wavelength (λ) is 2 meters.
