Waves

Front

What is reflection in the context of waves?

Back

Reflection occurs when a wave strikes an object and bounces off, such as an echo.

Front

Define wavelength.

Back

Wavelength is measured as the length from a wave's crest to crest or trough to trough.

Front

What type of wave behavior occurs when a wave bounces off a surface?

Back

Reflection.

Front

How can you identify the wave with the greatest wavelength in a diagram?

Back

The wave with the greatest wavelength will have the longest distance between consecutive crests or troughs.

Front

Through which mediums can sound travel?

Back

Sound can travel through solid, liquid, and gas; therefore, it can travel through all of the above.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, changing speed.

Front

Explain diffraction.

Back

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

Front

What is amplitude in wave terminology?

Back

Amplitude is the maximum distance that the wave moves from its rest position, indicating the wave's energy.

Front

What is the difference between constructive and destructive interference?

Back

Constructive interference occurs when waves combine to make a larger wave, while destructive interference occurs when waves combine to make a smaller wave.

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.
