EM Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

Which color of visible light has the longest wavelength?

Back

Red has the longest wavelength in the visible light spectrum.

Front

Which color of visible light has the shortest wavelength?

Back

Violet has the shortest wavelength in the visible light spectrum.

Front

What type of electromagnetic radiation is used in radar technology?

Back

Radar technology uses microwaves.

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

Which type of electromagnetic radiation has the highest frequency?

Back

Gamma rays have the highest frequency in the electromagnetic spectrum.

Front

What are radiowaves used for?

Back

Radiowaves are used for communication, including radio and television broadcasting.

Front

What is the wavelength range of visible light?

Back

The wavelength range of visible light is approximately 400 to 700 nanometers.

Front

What type of electromagnetic radiation is used for cooking food in microwave ovens?

Back

Microwaves are used for cooking food in microwave ovens.

Front

What is ultraviolet radiation?

Back

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