Waves Properties, Interactions, EM Spectrum

Front

What is frequency in the context of waves?

Back

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

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What does a wave carry from place to place?

Back

A wave carries energy from one location to another.

Front

Why does an object appear a certain color, like red?

Back

An object appears red because it absorbs all colors of light except red, which it reflects.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, X-rays, and more.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.
