Bell Ringer SC.7.P.10.3

Front

What happens to the speed of a sound wave as it passes from the air into the ground?

Back

It increases.

Front

Which choice identifies a property of sound waves?

Back

They will travel faster through solid materials and get progressively slower through liquids and gases.

Front

How do the sound waves of the higher pitch notes compare to the sound waves of the lower pitch notes?

Back

The sound waves of notes with higher pitches have higher frequencies.

Front

What happens to the speed of light as it exits the air and enters a glass of water?

Back

It slows down.

Front

What happens when light is refracted?

Back

It changes direction.

Front

Define sound wave.

Back

A sound wave is a type of mechanical wave that is created by vibrating objects and travels through a medium such as air, water, or solids.

Front

What is frequency in relation to sound waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound; higher amplitude means louder sound.

Front

What is the relationship between wavelength and pitch?

Back

Shorter wavelengths correspond to higher pitches, while longer wavelengths correspond to lower pitches.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.
