Question

The pattern of this wave changes between its beginning and end. What is true about the amplitude and wavelength of the wave when the pattern changes? A) Both the amplitude and wavelength of the wave increase. B) Both the amplitude and wavelength of the wave decrease. C) The amplitude of the wave increases while the wavelength decreases. D) The amplitude of the wave decreases while the wavelength increases.

Answer 1

Option D

The amplitude of the wave decreases while the wavelength increases is true about the amplitude and wavelength of the wave when the pattern changes

Explanation:

Amplitude is the distance within the resting point and the supreme displacement of the wave. Amplitude covers how much energy is staying carried by the wave. The greater the amplitude, the higher the energy a wave has. The wavelength is the distance within contiguous identical parts of a wave, identical to the direction of propagation.

The wavelength can also be considered as the distance a wave has progressed after one complete cycle. When the pattern shifts in any way then the amplitude of the wave decreases while the wavelength increases.

Answer 2

The amplitude of the wave decreases while the wavelength increases when the pattern changes-Option D

Explanation:

Amplitude can be defined as the  distance within the peak point and the trough  of the wave.

Both amplitude and the wavelength are both measures of distance.Th wavelength measures the horizontal distance between the waves while the amplitude measures the height of the crest.

The amplitude of a wave is the height of a wave as measured from the highest point on the wave which is called the peak or crest, to the lowest point on the wave which is called the trough.

Wavelength refers to the length of a wave from one peak to the next.

The amplitude of the wave decreases while the wavelength increases when the pattern changes-Option D
