What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (like air, water, or solids) by vibrating particles.

Front

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as from crest to crest or trough to trough.

Front

What is frequency in sound waves?

Back

Frequency is the number of waves that pass a given 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 maximum displacement of points on a wave from its rest position, which determines the loudness of the sound.

Front

How does wavelength affect pitch?

Back

As wavelength increases, pitch decreases. Longer wavelengths correspond to lower frequencies and lower pitches.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is diffraction in sound waves?

Back

Diffraction is the bending of waves around obstacles or through openings, allowing sound to be heard even when the source is not in direct line of sight.

Front

What is reflection in sound waves?

Back

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

Front

What is refraction in sound waves?

Back

Refraction is the change in direction of sound waves as they pass from one medium to another, due to a change in speed.

Front

What is interference in sound waves?

Back

Interference occurs when two or more sound waves overlap, resulting in a new wave pattern that can be constructive (louder) or destructive (softer).
