Waves, Light, and Sound

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through matter or space, often characterized by oscillations.

What is the speed of sound in air compared to water?

Back

Sound travels faster in water than in air due to the closer proximity of molecules in water.

Front

What is the cochlea?

Back

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

Front

What is amplitude in a wave?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from the rest position to the crest or trough.

Front

What is the difference between a crest and a trough?

Back

A crest is the highest point of a wave, while a trough is the lowest point.

Front

How does sound travel through different mediums?

Back

Sound travels fastest through solids, slower through liquids, and slowest through gases due to differences in molecular density.

Front

What is the relationship between frequency and pitch?

Back

Frequency is the number of waves that pass a point in a given time, and it determines the pitch of the sound; higher frequency means higher pitch.

Front

What is light?

Back

Light is a form of electromagnetic radiation that is visible to the human eye.

Front

What is refraction?

Back

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

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.
