Waves, Sound & Light

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What is a medium in the context of sound?

Back

A medium is a substance through which sound waves can travel, such as air, water, or solids.

Front

What happens to an object with a density greater than water when placed in it?

Back

It will sink.

Front

Which state of matter allows sound to travel the fastest?

Back

Sound travels fastest in solids.

Front

What is frequency in relation to waves?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is reflection in terms of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier.

Front

What is absorption in the context of sound?

Back

Absorption is the process by which sound energy is taken in by a material, reducing the sound's intensity.

Front

What is scattering in relation to light?

Back

Scattering is the redirection of light in different directions when it strikes small particles.

Front

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

Back

Approximately 343 meters per second.
