ie sound

Front

What is the definition of sound?

Back

Sound is a form of energy that travels in waves and is produced by vibrating objects.

Front

What are the main properties of sound waves?

Back

The main properties of sound waves include frequency, wavelength, amplitude, and speed.

Front

How does frequency affect the pitch of a sound?

Back

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

Front

What is the relationship between amplitude and loudness?

Back

Greater amplitude results in louder sounds, while smaller amplitude results in softer sounds.

Front

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

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is the difference between pitch and loudness?

Back

Pitch refers to how high or low a sound is, while loudness refers to the perceived intensity of a sound.

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What are the different types of sound waves?

Back

Sound waves can be classified as longitudinal waves and transverse waves, with longitudinal waves being the most common in air.

Front

What is resonance in the context of sound?

Back

Resonance is the phenomenon where an object vibrates at its natural frequency due to an external force.
