Waves

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through and cannot propagate through a vacuum.

Front

What is the lowest point on a wave called?

Back

The lowest point on a wave is called the Trough.

Front

What is the correct order of waves on the Electromagnetic Spectrum from lowest to highest frequency?

Back

The correct order is: Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma.

Front

How do you measure the wavelength of a sound wave?

Back

Wavelength is measured from compression to compression.

Front

What are frequencies above the human hearing range called?

Back

Frequencies above the human hearing range are called ultrasonic.

Front

What is amplitude in the context of waves?

Back

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

Front

Define wavelength.

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the displacement is parallel to the direction of wave propagation.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance traveled by a wave in a given amount of time, calculated as speed = wavelength × frequency.

Front

What is the principle of superposition?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.
