Electromagnetic Spectrum

Front

What is the electromagnetic spectrum (EMS)?

Back

The electromagnetic spectrum (EMS) 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 type of electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

As the frequency of an electromagnetic wave increases, its wavelength decreases.

Front

What is the relationship between frequency and energy in electromagnetic waves?

Back

As the frequency of an electromagnetic wave increases, the energy of that wave also increases.

Front

Define amplitude in the context of electromagnetic waves.

Back

Amplitude is the height of the wave from the rest position, indicating the strength or intensity of the wave.

Front

List the types of electromagnetic waves in order from longest wavelength to shortest wavelength.

Back

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

Front

What is the frequency range of radio waves?

Back

Radio waves typically have frequencies ranging from about 3 kHz to 300 GHz.

Front

What is the significance of the visible spectrum in the electromagnetic spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 400 nm (violet) to 700 nm (red).

Front

How do microwaves differ from radio waves?

Back

Microwaves have shorter wavelengths and higher frequencies than radio waves, typically ranging from 1 mm to 1 m.

Front

What is ultraviolet radiation and its effects on human health?

Back

Ultraviolet (UV) radiation is a type of electromagnetic radiation with wavelengths shorter than visible light; it can cause skin damage and increase the risk of skin cancer.
