Sound Flashcard

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travels through air, water, or solid materials.

Front

How does sound travel through different materials?

Back

Sound travels fastest through solids (like steel) because the particles are closer together, allowing vibrations to pass more quickly.

Front

What is frequency in relation to sound?

Back

Frequency is the number of vibrations or cycles per second of a sound wave, which determines the pitch of the sound.

Front

What is pitch?

Back

Pitch is how high or low a sound is, which is determined by the frequency of the sound wave.

Front

What is amplitude?

Back

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

Front

What is the ear drum?

Back

The ear drum is a thin membrane that vibrates when sound waves hit it, allowing us to hear.

Front

What is the role of the cochlea?

Back

The cochlea is a spiral-shaped organ in the inner ear that converts sound vibrations into electrical signals for the brain.

Front

What is diffraction in sound?

Back

Diffraction is the bending of sound waves around obstacles, allowing us to hear sounds even when they are not in a direct line of sight.

Front

What is reflection in sound?

Back

Reflection is when sound waves bounce off a surface, which can create echoes.

Front

What is interference in sound?

Back

Interference occurs when two sound waves meet and combine, which can amplify or cancel out the sound.
