Brody and ethel are arguing about waves. brody says that waving his hand back and forth is a scientific wave. ethel says that it is not. which statement best describes who is correct? -brody is correct because the wave involves an input of energy. -ethel is correct because energy is not carried from one place to another. -brody is correct because the pattern repeats. -ethel is correct because the motion has no pattern. khalad is measuring the amplitude of a wave. what can be known about this wave? -it is a sound wave. -it is a transverse wave. -it is an electromagnetic wave. -it is a mechanical wave.

Ethel is correct because energy is not carried from one place to another.

It is a transverse wave.

Explanation:

During the propagation of waves from one point or place to another, energy is being transferred. Thus, when one's hand is being waved, there is no transfer of energy from one point to another. Therefore, Ethel is right while Brody is wrong.

A transverse wave is known as a type of wave that the direction of propagation is perpendicular to the vibration of the medium. Therefore, the wave is a transverse wave.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
