Electromagnetic 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

What happens to the frequency of waves as their wavelength increases?

Back

As the wavelength of electromagnetic waves increases, their frequency decreases.

Front

What type of radiation is visible light?

Back

Visible light is a part of the electromagnetic spectrum that can be seen by the human eye.

Front

What is ultraviolet (UV) radiation?

Back

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

Front

How does ultraviolet radiation compare to visible light in terms of wavelength?

Back

Ultraviolet radiation has shorter wavelengths than visible light.

Front

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

Back

The energy of electromagnetic waves is directly proportional to their frequency; higher frequency waves have more energy.

Front

What are the two types of ultraviolet radiation?

Back

The two types of ultraviolet radiation are UVA and UVB.

Front

What is the danger of high-frequency electromagnetic waves?

Back

High-frequency electromagnetic waves, such as X-rays and gamma rays, can be more hazardous due to their higher energy levels.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves.

Front

What is the primary source of electromagnetic radiation on Earth?

Back

The primary source of electromagnetic radiation on Earth is the Sun.
