Waves and Electromagnetic Spectrum

Front

What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from red (longer wavelength) to violet (shorter wavelength).

Front

What is the correct order of the visible light spectrum starting with the longer wavelength?

Back

Red, orange, yellow, green, blue, indigo, violet.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation, such as in light waves.

Front

What is the highest point on a transverse wave called?

Back

Crest.

Front

What is the lowest point on a transverse wave called?

Back

Trough.

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position to its crest or trough, representing the energy of the wave.

Front

What is wavelength?

Back

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

Front

What medium do sound waves travel fastest through?

Back

Sound waves travel fastest through solids.

Front

What is frequency in relation to waves?

Back

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

Front

What is wave speed?

Back

Wave speed is the distance a wave travels per unit of time, calculated as wave speed = frequency × wavelength.
