Intro to Waves

Front

What type of energy does a sound wave have?

Back

Mechanical energy is the energy associated with the motion and position of an object.

Front

Sound waves travel the fastest through which medium?

Back

Sound waves travel fastest through solids because the particles are closer together, allowing for quicker transmission of energy.

Front

Why do we see grass as green?

Back

Grass appears green because it reflects green light and absorbs other colors of light.

Front

What is the term for the number of wavelengths that pass a fixed point each second?

Back

Frequency is measured in Hertz (Hz) and indicates how often a wave cycles in one second.

Front

What is transferred by a wave?

Back

Waves transfer energy from one location to another without transferring matter.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Front

What is amplitude in a wave?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particle displacement is parallel to the direction of wave propagation, like sound waves.
