Question

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. Also... 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.

Answer 1

Answer:

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.

Answer 2

In the first question, the answer would be the statement 'Brody is correct because the wave involves an input of energy'. The hand wave involves an input of energy and this energy is repeated and is carried from one place to another. 

For the next question, the answer would be 'it is a transverse wave' because all are transverse waves.
