Answer 1

option C)

The wavelength has a length between 7.0 cm and 8.0 cm and the amplitude lies between 1.0 cm and 2.0 cm.

Step-by-step explanation

1)

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

By looking at the image

rest point is at 5cm and crest is at 3.3 cm (y-axis)

so amplitude = 5 - 3.3

= 1.7 cm (approximately)

2)

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

one crest is at 2cm and the other crest is at 10cm (x-axis)

so wavelength = 10 - 2

= 8 cm (approximately)
