Noe is studying wave a and wave b. wave a is rated at 100 db, and wave b is rated at 90 db. which statement can be made about the waves? wave a has fewer decibels than wave b. wave a is louder than wave b. the intensity of both waves is the same. the amplitude of both waves is the same.

B.  Wave A is louder than Wave B.

Explanation: The loudness of sound is measured in unit called decibels (dB).

A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.

Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.

Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.
