Question

1. which of the following statements accurately compares the wavelengths of the waves shown below

wave 1 has a shorter wavelength than wave 2.
wave 1 and wave 2 have the same wavelength.
wave 2 has a longer wavelength than wave 1.
wave 1 has a longer wavelength than wave 2.

Explanation:

Wavelength is the distance between two consecutive crests (or troughs) of a wave. In the given diagrams, Wave 1 has fewer cycles (peaks and troughs) in the same length of space compared to Wave 2. Fewer cycles mean larger distance between consecutive crests (or troughs), so Wave 1 has a longer wavelength.

Answer:

Wave 1 has a longer wavelength than wave 2.
