Question 4 Which of the following best describes the relationship between wave amplitude and decibels? A As amplitude increases, the wavelength of the decibels increases. B C D As amplitude increases, decibels increase. Decibels and amplitude have an inversely proportional relationship. As amplitude decreases, decibels increase.
