(i will mark brainliest) what part of the wave does “d” represent?

question options:

d the compression

b the wavelength

c the crest

a the amplitude

what part of the wave does “c” represent?

question options:

a the amplitude

b the wavelength

c the crest

d the compression

Answer : The correct answer for 'd' is B The Wavelength and 'c' is A the amplitude.

'd' is showing the distance between two peaks of a wave which is a wavelength . Wavelength is defined as distance between two similar part of a wave like distance between two peaks or two troughs . It is also known as length of one full wave or one full oscillation of a wave .So 'd' is B the wavelength .

'c' shows the height of the peak . The height of the peak is called as Amplitude of wave which is defined as the vertical distance between the central line (resting position of wave )and peak or trough . Hence 'c' presents Amplitude of the wave .So correct option for 'c' is A the amplitude

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
