Light and Light Waves

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through. They can be classified as transverse or longitudinal waves.

Front

What happens when light shines through a prism?

Back

When light shines through a prism, it creates visible light, which is a spectrum of colors.

Front

What is wave height also known as?

Back

Wave height is also known as amplitude.

Front

What are compressions in waves?

Back

Compressions are regions in longitudinal waves where particles are close together.

Front

Does a larger amplitude mean less energy in a wave?

Back

False. A larger amplitude means more energy in a wave.

Front

What are transverse waves?

Back

Transverse waves are waves where the particle movement is perpendicular to the direction of wave propagation.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves where the particle movement is parallel to the direction of wave propagation.

Front

What is the definition of wavelength?

Back

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

Front

What is frequency in terms of waves?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

The relationship is inversely proportional; as frequency increases, wavelength decreases.
