Espectro electromagnético

The video tutorial explains the electromagnetic spectrum, which encompasses all types of electromagnetic radiation. It ranges from gamma rays, with very short wavelengths, to longwave radiation emitted by interstellar cold matter, which can have wavelengths exceeding 1,000,000 kilometers.

What does the electromagnetic spectrum encompass?

• Only visible light

• All types of electromagnetic radiation

• Only gamma rays

• Only radio waves

Which type of electromagnetic radiation has wavelengths smaller than an atom?

• Radio waves

• Microwaves

• Infrared radiation

• Gamma rays

What is the characteristic of gamma rays in terms of wavelength?

• Equal to the size of a molecule

• Larger than visible light

• Larger than a human cell

• Smaller than the size of an atom

What type of radiation is emitted by interstellar cold matter?

• Ultraviolet radiation

• Longwave radiation

• X-rays

• Gamma rays

How long can the wavelengths of longwave radiation be?

• Exactly 500 kilometers

• Between 1 and 100 kilometers

• More than 1000,000 kilometers

• Less than 1 kilometer
