Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is wavelength?

Back

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

Front

What type of electromagnetic radiation has the highest energy?

Back

X-rays have the highest energy among the options provided.

Front

What is frequency in the context of waves?

Back

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

Front

What is the order of electromagnetic waves from lowest to highest energy?

Back

The order is: Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with the longest wavelength and lowest frequency, used for communication.

Front

What is the speed of light?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is amplitude?

Back

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

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye, ranging from approximately 400 to 700 nanometers.

Front

What is ultraviolet (UV) radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays, often associated with sunburn.
