TN Ready Practice Test for PS4.1-4.3 Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its wavelength, frequency, and amplitude.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

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 sound?

Back

Sound is a type of mechanical wave that travels through a medium (solid, liquid, or gas) and is perceived by our ears.

Front

What happens to sound waves as they get louder?

Back

As sound waves get louder, their amplitude increases.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye, ranging from red to violet.

Front

Why does an apple appear red?

Back

An apple appears red because it reflects red wavelengths of light and absorbs other wavelengths.

Front

What material is commonly used to block x-ray waves?

Back

Lead is commonly used to block x-ray waves due to its density and ability to absorb radiation.
