Waves Test Review

Front

What is reflection in wave behavior?

Back

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

Front

How does increasing the amplitude of a sound wave affect its loudness?

Back

Increasing the amplitude of a sound wave makes it louder.

Front

What is an echo an example of?

Back

An echo is an example of sound wave reflection.

Front

What type of interference do noise cancelling headphones use?

Back

Noise cancelling headphones use destructive interference to reduce unwanted sounds.

Front

What type of materials allow light waves to pass through easily?

Back

Transparent materials allow light waves to pass through easily.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material, reducing the wave's intensity.

Front

What is the difference between constructive and destructive interference?

Back

Constructive interference occurs when waves combine to make a larger wave, while destructive interference occurs when waves combine to reduce or cancel each other out.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

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

Back

Higher frequency sound waves produce a higher pitch, while lower frequency sound waves produce a lower pitch.

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.
