Front

What happens to the loudness of a sound as the amplitude of a sound wave increases?

Back

The louder a sound becomes.

Front

What type of rays can take pictures inside the body of bones and teeth?

Back

Front

What occurs when light waves pass through the lens of a camera or your eye?

Back

They refract and then form an image at a focal point.

Front

What does the pitch (highness or lowness) of a sound depend on?

Back

Frequency.

Front

Define amplitude in the context of sound waves.

Back

Amplitude is the height of the wave, which determines the loudness of the sound.

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation, including radio waves, visible light, and gamma rays.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What are infrared rays used for?

Back

Infrared rays are used in thermal imaging and remote controls.
