Wave Properties of Light & Sound

Front

What is the definition of sound amplitude?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In sound, it relates to the loudness of the sound.

Front

What is frequency in relation to sound?

Back

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

Front

What is visible light?

Back

Visible light is a form of energy that can be seen by the human eye, part of the electromagnetic spectrum.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, infrared, ultraviolet, and more.

Front

What color of light has the highest energy?

Back

Violet light has the highest energy in the visible spectrum.

Front

What color of light has the lowest energy?

Back

Red light has the lowest energy in the visible spectrum.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is the difference between mechanical waves and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel through, while electromagnetic waves do not require a medium and can travel through a vacuum.

Front

What is an example of a mechanical wave?

Back

Sound waves are an example of mechanical waves.
