Electromagnetic Spectrum Quiz (for AES SBB)

What is the electromagnetic spectrum?

• The different types of clouds in the sky

• A type of musical instrument

• Range of all types of electromagnetic radiation

• The range of colors visible to the human eye

List the different types of waves in the electromagnetic spectrum.

• red waves, blue waves, green waves

• hot waves, cold waves, warm waves

• big waves, small waves, medium waves

• radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays

Which type of wave in the electromagnetic spectrum has the longest wavelength?

• Gamma rays

• Radio waves

• X-rays

• Ultraviolet waves

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

• Constant

• Inverse

• Direct

• Unrelated

Explain the concept of reflection of electromagnetic waves.

• When an electromagnetic wave strikes a surface, it bounces back instead of being absorbed.

• The angle of reflection of electromagnetic waves is always greater than the angle of incidence.

• When an electromagnetic wave passes through a surface, it gets absorbed completely.

• Reflection of electromagnetic waves only occurs in a vacuum.

How does the speed of the waves in the electromagnetic spectrum change as these waves travel through first in vacuum, in air follows by water and finally in glass ?

• It increases

• It decreases

• It stays the same

• It becomes invisible

What is the role of the electromagnetic spectrum in technologies like radio, microwave, and X-ray?

• It has no role in these technologies

• It provides the range of frequencies and wavelengths used for communication, heating, and imaging.

• It is only used for visual light

• It is only used for generating heat

Describe the process of absorption of electromagnetic waves.

• Absorption of electromagnetic waves occurs when the energy of the waves is taken in by the material they encounter.

• Absorption of electromagnetic waves occurs when the energy of the waves is converted into sound waves by the material they encounter.

• Absorption of electromagnetic waves occurs when the energy of the waves is released by the material they encounter.

• Absorption of electromagnetic waves occurs when the energy of the waves is reflected by the material they encounter.

Discuss the impact of the electromagnetic spectrum on human health and the environment.

• Exposure to radiation from devices like microwaves and toasters, as well as potential effects on plant growth.

• Exposure to radiation from devices like cell phones and Wi-Fi, as well as potential effects on wildlife and ecosystems.

• The electromagnetic spectrum has no impact on human health or the environment.

• The electromagnetic spectrum only affects electronic devices and has no impact on living organisms.
