Question

Compare the patterns of the two waves shown in the image. Which statement is true about these waves?

A) Wave A has a shorter wavelength than Wave B.

B) Wave B has a shorter wavelength than Wave A.

C) They have different amplitudes but the same wavelengths.

D)They have different wavelengths but the same amplitudes.

Answer 1

Answer:

B) Wave B has a shorter wavelength than Wave A.

Explanation:

The images shown by waves A and B presents two waves with different amplitudes and wavelengths.

Wavelength:

• The wavelength of a wave is the distance between two successive peaks and troughs.
• Just merely looking at the two waves shows two entities of different wavelength.

Amplitude:

• This is the maximum vertical displacement of the wave
• It is the extent of the wave in the vertical direction from are reference
• It is clearly shown that the first wave has a higher vertical displacement.

The two waves clearly have different wavelengths and  amplitude.

Answer 2

Answer:

Wave B has a shorter wavelength than Wave A.

Explanation:

Wavelength is the distance between one crest or trough to the next; B's wavelength is shorter than A's wavelength.
