Wave Characteristics

The throwing back by a wall or barrier of a sound wave without absorbing it.

• Refraction

• Diffraction

• Reflection

• Absorption

When a wave is being absorbed by an object.

• Refraction

• Diffraction

• Reflection

• Absorption

When a wave bends sharply through a narrow space.

• Refraction

• Diffraction

• Reflection

• Absorption

When a wave changes direction as they pass from one medium to another.

• Refraction

• Diffraction

• Reflection

• Absorption

What does reverberation mean according to reflection?

• Reverberation is how sound waves bounce from one barrier to another.

• Reverberation is the prolonged sound of a sound wave in a person’s ear.

• Reverberation is the sound waves communicating .

How does echolocation work? (Use bats as an example).

• Echolocation is the use of sound waves and echoes to determine where objects are in space, using reflection.

• Echolocation is when the pray makes the sound for the animal to hear.

• Echolocation is the use of sound waves turning in a sharp detection because of passing through a narrow pathway.

How do walls or barriers affect waves?

• Walls and barriers affect waves in by allowing waves to bounce back.

• Walls and barriers affect waves in two ways, waves can bounce back, or become absorbed.

• Walls and barriers affect waves in three ways, waves can bounce back, become absorbed, or pass through.

What is the difference between diffraction and refraction?

• Diffraction is the bending of waves as a result of the waves going to a small passage way. Refraction in the other hand, is the bending of a wave as the it moves to another medium.

• Diffraction is is the bending of a wave as the it moves to another medium. Refraction in the other hand, is the bending of waves as a result of the waves going to a small passage way.

• Diffraction is the bending of waves as a result of the waves bouncing from a barrier/wall. Refraction in the other hand, is the bending of a wave as it hits another wave.

What affects the amplitude of a sound wave?

• The amount of mass that is put into a wave determines its amplitude.

• The amount of gravity that is put into a wave determines its amplitude.

• The amount of energy that is put into a wave determines its amplitude.

Which of the following is the best example of why it is important to know what wave characteristics are in real life?

• Understanding how color blind people see (biology).

• Understanding how the ear and brain work (biology).

• Understanding how to make a better sounding car (engineer).
