Q3 Science Benchmark Review

Front

What happens to the pitch of a sound wave if the wavelength increases?

Back

The pitch of the sound wave decreases, resulting in a lower pitch.

Front

What is refraction in wave interactions?

Back

Refraction is the bending of waves as they pass from one medium to another, changing speed.

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction.

Front

In which types of changes does the Law of Conservation of Mass apply?

Back

The Law of Conservation of Mass applies to both chemical and physical changes.

Front

Which color of visible light has the highest frequency?

Back

Violet light has the highest frequency among visible colors.

Front

What is the relationship between wavelength and pitch in sound waves?

Back

As the wavelength increases, the pitch decreases.

Front

Define diffraction in the context of wave behavior.

Back

Diffraction is the spreading of waves when they encounter an obstacle or pass through a narrow opening.

Front

What is interference in wave interactions?

Back

Interference occurs when two or more waves overlap and combine to form a new wave pattern.

Front

Explain the concept of reflection in wave behavior.

Back

Reflection is the bouncing back of a wave when it hits a barrier.

Front

What is the difference between chemical and physical changes?

Back

Chemical changes result in new substances, while physical changes do not alter the substance's chemical composition.
