Test: Evaluating 5G Technology

What type of wave is a microwave, and why is it important to how cell phones operate?

• A sound wave; it allows for clear audio transmission

• A radio wave; it helps signals travel long distances

• An electromagnetic wave; it enables wireless communication

• A mechanical wave; it requires a medium to travel

Compared to x-rays, how do the energy and wavelength of microwave signals used in 4G and 5G compare?

• Microwaves have lower energy and longer wavelengths than x-rays

• Microwaves have higher energy and shorter wavelengths than x-rays

• Microwaves and x-rays have the same energy and wavelength

• Microwaves do not travel through air like x-rays do

Which of the following characteristics best represents a 5G wave compared to a 4G wave?

• Lower amplitude and lower frequency

• Higher amplitude and lower frequency

• Higher frequency and shorter wavelength

• Lower frequency and longer wavelength

How do 5G and 4G electromagnetic waves compare in relation to energy, wavelength, and speed?

• 5G has lower energy, longer wavelength, and the same speed as 4G

• 5G has higher energy, shorter wavelength, and the same speed as 4G

• 5G has lower energy, shorter wavelength, and slower speed than 4G

• 5G has higher energy, longer wavelength, and faster speed than 4G

When a 5G signal enters a fiber optic cable where the speed of light is slower, what happens to its wavelength?

• It increases

• It decreases

• It stays the same

• It disappears

• 1.07 x 10^{-2} m; 8.93 x 10^{-3} m

Which of these electromagnetic waves should travel faster through air?

• 5G, because it has a higher frequency

• 4G, because it has a longer wavelength

• Both travel at the same speed in air

• Neither can travel through air 

What is the difference between analog and digital formats for voice calls?

• Analog is continuous, while digital is discrete

• Digital has lower sound quality than analog

• Analog allows for better storage efficiency

• Digital signals are less reliable than analog

How does switching to digital impact the company’s ability to store phone calls?

• Digital calls take up more space due to high-quality storage

• Digital calls take up less space since they are compressed

• Analog calls are easier to store than digital

• There is no difference in storage needs

How does a digital signal impact the sound quality of a phone call?

• It decreases sound quality due to missing data

• It improves sound quality due to reduced noise and interference

• It has no effect on sound quality

• It makes sound quality worse because it is converted into binary
