Waves and Electromagnetic Radiation Pre-Test

Front

What are the properties of electromagnetic waves?

Back

Wavelength, frequency, amplitude, and speed.

Front

Name three types of electromagnetic waves and provide an example of each.

Back

Radio waves (example: FM radio), visible light (example: sunlight), and X-rays (example: medical imaging).

Front

How are electromagnetic waves used in everyday life?

Back

They are used for communication (like cell phones), cooking (like microwaves), medical imaging (like X-rays), and more.

Front

Explain the electromagnetic spectrum and its different regions.

Back

The electromagnetic spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

How do gamma rays differ from other types of electromagnetic waves?

Back

Gamma rays have higher frequency and energy.

Front

What is wavelength in the context of electromagnetic waves?

Back

Wavelength is the distance between successive peaks of a wave.

Front

What is frequency in the context of electromagnetic waves?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is amplitude in the context of electromagnetic waves?

Back

Amplitude is the height of the wave from its rest position, indicating the energy of the wave.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

What are radio waves used for?

Back

Radio waves are used for communication, including radio and television broadcasting.
