Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is frequency in the context of waves?

Back

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

Front

What happens to the speed of a wave when it passes from one medium to another?

Back

The speed of a wave may change when it passes from one medium to another.

Front

What is wavelength?

Back

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

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle displacement is parallel to the direction of wave propagation (e.g., sound waves). In transverse waves, the particle displacement is perpendicular to the direction of wave propagation (e.g., light waves).

Front

What is a medium in the context of wave propagation?

Back

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

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum because it requires a medium (solid, liquid, or gas) to propagate.

Front

What is reflection in terms of wave behavior?

Back

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

Front

What is refraction?

Back

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

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.
