Front

What is compression in a longitudinal wave?

Back

Compression is the region in a longitudinal wave where the particles are closest together, resulting in increased pressure.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing a change in speed and direction.

Front

What is the process of changing from a liquid to a gas called?

Back

The process of changing from a liquid to a gas is called evaporation.

Front

What is the speed of sound in different states of matter?

Back

The speed of sound is generally greatest in solids, lower in liquids, and lowest in gases.

Front

What happens to white light when it passes through a prism?

Back

White light is refracted and scattered by the prism, resulting in a spectrum of colors, often seen as a rainbow.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and openings, leading to interference patterns.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light when it hits a surface, while refraction is the bending of light as it passes through different media.

Front

What is the definition of frequency?

Back

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

Front

What is the relationship between temperature and the state of matter?

Back

Increasing temperature can cause a substance to change from solid to liquid (melting) or from liquid to gas (evaporation).
