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

Which EM waves have the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

What is the relationship between wavelength and frequency?

Back

As the wavelength decreases, the frequency increases.

Front

What happens to energy when frequency increases?

Back

The energy of electromagnetic waves increases as the frequency increases.

Front

Which EM waves have the lowest frequency?

Back

Radio waves have the lowest frequency in the electromagnetic spectrum.

Front

What type of EM waves are used in microwave ovens?

Back

Microwaves are the type of electromagnetic waves used in microwave ovens.

Front

What is the wavelength range of visible light?

Back

Visible light has a wavelength range of approximately 400 to 700 nanometers.

Front

Which EM waves have a shorter wavelength than visible light?

Back

Ultraviolet rays, x-rays, and gamma rays have shorter wavelengths than visible light.

Front

What is the frequency of a wave with a wavelength of 2 meters?

Back

The frequency can be calculated using the formula: frequency = speed of light / wavelength. For a wavelength of 2 meters, the frequency is approximately 150 MHz.

Front

What are x-rays used for?

Back

X-rays are commonly used in medical imaging to view the inside of the body.
