Waves

Front

What is refraction?

Back

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

Front

What happens to a wave's speed when it enters a different medium?

Back

The speed of the wave changes depending on the properties of the new medium.

Front

What is a medium in the context of waves?

Back

A medium is the matter through which a wave travels, such as air, water, or solid materials.

Front

What is reflection in wave behavior?

Back

Reflection is when a wave bounces off an object instead of passing through it.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings.

Front

What type of waves are sound waves?

Back

Sound waves are compressional waves, meaning they compress and expand the medium they travel through.

Front

What is the difference between transverse and compressional waves?

Back

Transverse waves move perpendicular to the direction of the wave, while compressional waves move parallel to the direction of the wave.

Front

What is the principle of superposition in wave interference?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

What is the frequency of a wave?

Back

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

Front

What is wavelength?

Back

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